In the myth that throwing a fire extinguisher on a fire will cause it to explode and put out the fire, the team had already had two failures, both of which took several minutes to fail. Now they tested the third extinguisher, full of chemical foam, which led to this unbelievable exchange just seconds after they dropped it in.
Tory: Anyone bring any cards? Grant: Let's do charades. Tory: Okay, you first. Two words! Grant:(cracks up laughing) I-I can't do this! Tory:Sounds like? BOOM Everyone: Oh my God, it put out the fire! I can't believe it! It exploded and put out - wait, is it raining chemical foam? Oh God, that's nasty!
Grant and Tory built a turkey-dropping rig and gave it a pair of plastic hands. As they tested the rig, the arms slammed together, and the plastic hands utterly shattered. The completely shocked looks on Tory and Grant's faces were funny enough, but the crown on the Crowning Moment comes when Kari walked in, holding a piece of one of the hands, and completely deadpanned:
Do we want to talk about why I just got hit in the head with a thumb?
Anything involving the hideous ballistics gel dog is golden, especially Kari's bizarre Cuteness Proximity fondness for it.
The MythBusters also have a habit of overkill. The example that comes immediately to mind is shooting a fish in a barrel...with a gatling gun. Because any confirmation involving guns needs More Dakka.
"If it's worth doing, it's worth overdoing."
Testing the myth of a cell phone causing an explosion at a gas station, Adam and Jamie quickly discover their small scale test isn't quite small enough when it produces a huge fireball. Knowing he probably was, Adam asks:
Not just that. It's revealed in a later episode (a retrospective) that he had a date the next night, and was going to propose! Fortunately, in spite of the missing eyebrow and shorter hair (some of it was singed off along with the eyebrow), the date went great, and she said "yes"!
Jamie in the "Death by a falling penny" Myth. Jamie couldn't get the penny to fit in a staple gun, so he trims of the sides, fits it in and fires... without checking what may be overhead. Naturally the penny strikes a mercury lamp, shattering it. What makes it funnier is his sheepish grin followed by the matter-of-fact "We should get out of here. That's uh, mercury vapor there."
Also, Jamie using the modified penny gun to shoot Adam in the ass.
Jamie was, at that time, also the Mythbusters' safety officer. Make of it what you will.
During the Hammer vs. Hammer myth: Tory was trying to drive in a nail with one swing. He missed the nail twice, hitting the same spot both times.
The episode where they visit NASA to investigate the moon landing, and Grant spots a worryingly-labeled alarm:
Grant: Oxygen deficiency alarm? Is that something I should be worried about? NASA worker: Only if it goes off.
The Ming Dynasty Astronaut Myth. Basically, it's the myth that an wealthy astronomer from the Ming Dynasty strapped 47 rockets to his throne and, as eyewitnesses said, went into orbit in a puff of smoke, never to be seen again. After hearing that, we all know what really happened, but the humor comes in at the confirmation via giant explosion: in that puff of smoke, he didn't go up into orbit, he evaporated.
You can tell from the name of the first "Alcohol Myths" episode that it's going to be very funny, but quite how funny, you might not guess. Suffice to say, Adam, Jamie, and Kari are all hilarious drunks, but the highlight has to be Adam's attempt to test claims that exercise sobers you up quickly by running on a treadmill... which he falls off of. Twice. This is then followed by Adam testing the claim that a slap to the face (provided by Jamie) will sober you up. The high-speed footage was hysterical, and made even better by the fact that it actually worked.
Adam: That's the funniest thing I've ever seen!
In a different alcohol myth, Tory and Grant have to get drunk enough to get a hangover the next day. Twice. It's hilarious both times, especially when they try to go couch-surfing and when Tory jumps into bed from on top of a wall.
Tory's infamous cycling mishap. It's even funnier because while Tory was amusing himself out of earshot, Scottie suggested, "Let's egg him on until he hurts himself." She never expected he actually would.
It's even better in MythBusters Revealed / the Top 25 MythBusters Moments special, where Tory explains he went through with it specifically because Scottie and Kari said he could totally make it. (Kari insists she was being sarcastic.)
From the same episode, Adam gets his fingers caught in the door of the pick-up as Scotty slammed it shut. (Unintentionally of course. Adam was even quick to claim it wasn't even her fault.)
Adam getting shocked by the fake Ark of the Covenant after the build team wires it up to an electric fence.
Kari: Did you feel God?
This actually loses some of its humor when you see the outtakes. The whole story goes that Adam was expecting to get a tiny electric shock from the Ark being hooked up to the recreated "Baghdad Batteries," because they were testing the idea that it may have been used for religious purposes (to "feel God" as Kari put it). When he got actual pain, it's understandable why he was so pissed about it. Adam later explained in a Q & A that the suggestion came from a producer (who is "no longer with us") who thought it would be exciting TV. Even though it may have been quite funny to watch, Adam was seriously pissed off and once it happened no one, even the camera crew, thought it was particularly funny afterward. He said that pranks are a dangerous thing because A) they escalate into more outrageous and dangerous/illegal activities and B) they are people with some significant skills and resources at their disposal to make the pranks worse than any normal person could.
It gets its humor back when Adam tries to get his revenge in a later episode by setting off a homemade smoke bomb. He fails miserably, although the smoke bomb was remarkably resistant to attempts to put it out, which was funny enough on its own.
Another great moment involving electricity was when Adam, Jamie, Scottie, and Kari were playing with the Van der Graaf generator in the "static cannon" myth, the highlights of which have to be Scottie and Kari teasing Jamie for being skittish about getting shocked and all of them shocking Adam on the ass while he's got his hand on the generator.
As much humor as there was in that, it was also almost a Tear Jerker...all that work, wasted.
Although for more awesomeness, when they tried to test each individual aspect of the myth they busted the aspect of just how many individual bricks it took to make the ball. Why? Because they collected damn well near an entire country's worth of borrowed, used and new LEGO pieces just to get a tenth of the number of LEGO bricks specified in the video. They still made the ball, just not with the same number of bricks the video mentioned (they used 1 million bricks, instead of the 5 million stated in the video). Imagine having nearly a quarter as many LEGO bricks as they had.
In the "Bull in a China Shop" myth, Kari is talking to the producer about the shelves they've constructed to put in the pen for the bulls to trash. After a couple minutes of talking we see Tory run onscreen in the background, take a flying leap, and land with a crunch on one of said shelves. Kari doesn't even look around, but from the patently hilarious look on her face, she knows it was Tory without even looking, and she's exasperated, but to be surprised would be to give the impression she's never met him before. It's made funnier by the fact that he just lies there afterward.
The myth itself is also pretty hilarious. It sure looks like a Foregone Conclusion that the bulls will smash up everything, and the main concern is constructing harmless shelving that won't harm the bulls. Then the bulls completely bust the myth by nimbly running through the china shop, politely taking care not to disturb the proprietor's wares!
Turned Up to Eleven when they put as many as four bulls in there, and only one shelf (and one or two assorted pieces of china) got knocked over.
And again when it's revisited in the two hour Top 25 MythBusters Moments episode. Kari's voice over of just what the phrase "bull in a china shop" means is accompanied by a montage of Tory breaking things and hurting himself.
Tory and Grant are flying a mini-kite. It's unstable, so they tie a rock to the tail. Hilarity ensues.
Adam: Why, Thor, the God of Thunder, is trying to enter my building! Tory: Somebody needs to check that air conditioner!
At one point the suction gave out on one of Adam's climbers when testing it, smacking him on the head. Complete with a cartoonish "WHAM".
Jamie gets a wonderful Not So Stoic moment out of it too, while inside the duct.
Tory: Jamie, how you doing? Jamie:[giggle then a pause] I'm okay! [everyone laughs] Tory: Jamie do you think this is a practical way to get up a duct? [another pause] Jamie: Nope!
The narrator's description:
Narrator: Here's some key phrases from the 'Surreptitious Entry Heist Manual': Be the breeze. [KLANG] Light as a feather. [CRASH BONG] The footfall of a kitten. [KRASH KLANGKING BOM CRASHSHSHSHSH]
One YouTube commenter thinks that what he really means is: "Be the blow. Heavy as a brick. The footfall of Optimus Prime."
There was the time they tested smooth golf balls vs dimpled by having a pro golfer hit them. He complained the smooth ones were like hitting a brick.
Jamie (deadpan): I swapped it out when you weren't looking.
Later in the same episode, after the results are announced, Adam can't keep from giggling the whole time. Jamie's response just sets him off even worse.
Jamie: I feel like eating my beret. (Beat) Uh. I'm not gonna.
"Killer Brace Position", when they're finally ready to test it. You hear music and someone singing opera, then the camera shows ADAM, actually singing it!
Right before Adam, Kari and Tory were about to personally test keeping their heads back, Kari is hyperventilating into a paper bag, and Adam suddenly slams it.
Adam cooking a pot of wee to use as a cleaning agent in the Pirate special, complete with a hilariously bad French chef accent.
And Kari's sudden change of facial expression when the guys bring her in to judge the results and inform her that stale urine was one of the cleaners being tested. Her Flat "What." is almost audible.
After several failed attempts at beating a motion-sensing camera, Kari, Grant and Tory test whether holding a blanket up as you walk will help. None of them expect it to work, which makes it even funnier when they find out it does.
Then, there's the other way they attempt to foil the motion detector... by wearing a giant suit made out of yellow shag carpeting. The "chicken suit" is still in the background in many of the myth introduction shots.
Adam and Jamie training for their rooftop-chase-dumpster-dive myth. While Jamie is prepping for his first test jump, Adam grabs a megaphone and says, in a completely deadpan tone, "Jamie, don't jump, you've got so much to live for."
Pretty much any time that a myth gets introduced by an animation.
The one that really takes the cake is Finger in a Barrel, the myth about disabling a shotgun by plugging the barrel with a finger. The whole thing is presented like a Looney Tunes cartoon, complete with cartoonish caricatures of Jamie and Adam (later dubbed as "The Mythtoons") as "Hunter Hyneman" and "Savage Squirrel" respectively.
From the Diet Coke and Mentos segment, we have:
Narrator: Meanwhile, Adam, for reasons known only to himself, puts a bottle of Coke on the lathe. No prizes for guessing what happens next.
Cue the soda bottle (predictably) exploding. It's even better because some of the soda drips land on the camera lens.
In this "bloopers" feature, a close-up of flowers suddenly jumps to Adam giving a "viewer discretion is advised" warning. He then turns around and runs off into the background, showing that he's naked except for a large flowerpot held at groin level. Jamie just watches him go, and the camera crew can be heard cracking up when he hits his hip on the corner of the bench Jamie is standing behind. You can hear his "OW".
In one episode, Kari, Grant, and Tory, are testing to see if sound waves could be recorded on clay bottles. To test this, Tory screamed at a clay jar as they were etching into it with a needle.
Announcer: And Kari is about to say what every forensic scientist dreams of being able to say. Kari: YOU CRAZY KILLER!!
For the next two recording tests, she just yells, "TORY!!!" at the top of her voice. The second time, both Tory and the narrator deliver punchlines:
Narrator: The voice of an angel rings out... Kari: TORY!!! Narrator: ...or maybe, make that the devil. Tory: That was a good one, Kari. Now I know what it would be like to be married to you.
During the Myths Revisited first episode of Season 2, which is pretty much entirely hilarious, Adam is covered in gold paint, and has to have someone test his temperature...rectally. Medic Sanjay Singh does the deed. Cue Adam:
Adam: Oh, Sanjay, Sanjay, will you respect me tomorrow?
Compounded by the fact that Jamie Hyneman, Mister Flat Joy himself, is actually unable to finish the experiment because he can't stop laughing. And then there's the fact they used animal birthing lubricant as a counterpoint in slipperiness...
The episode where the myth of an empty beer bottle being a deadlier weapon than a full one involved making a gelatin brain to wobble inside of a clear "skull". After making the test, there was a segment where Adam, paraphrased, told it
"Remember when I built a robot that would swing a beer bottle into your head?" [reaches over with a spoon, spoons up and eats some of the gelatin] "Not anymore you don't! Mmm, what a delicious memory."
If you listen carefully, you'll notice that even Jamie starts to crack up (from off-camera)
From the Demolition Derby Special:
There is a car suspended from a crane. Kari: "Next on MythBusters, find out why we can't get car insurance."
When the car's roof gets shorn off by a tractor-trailer, it keeps going when the braking system fails and goes airborne off a small berm, clearing the chain fence behind it. You can immediately see Tory and Kari's faces shift from "This is Awesome!" to "Oh, Crap."
Tory: Hey, what's on the other side of that berm? Kari: Uh oh.
The foomf sound effect when they successfully try out their car ejector seat. It's the simple things, sometimes.
Not to mention the fact that it actually worked so well when they didn't quite expect it to do so at such a low air pressure setting (10 psi, as opposed to over 100 psi at its maximum setting which it was designed to operate), so they were caught by surprise. Also funny what happened to the seat - it not only cleared the car's roof, it also slammed the (open) trunk shut and cleared the partially closed garage door behind the car (in short, it went all the way out of the garage!).
During the "Escape From Alcatraz" myth, the team had to make a boat out of raincoats by pounding them together using quick drying cement.
Adam (Hammering a raincoat with a rubber mallet) Wait! (Jamie stops) Was that a guard? (Jamie chuckles) No! (BANGBANGBANGBANGBANGBANG)
The Hot-Blooded Stanford rowing coach for "Rowboat waterskier":
Bad formations did not get the man on the moon and will not get this Mythbuster out of the water! This is Apollo 13, baby, and Houston, we don't have a problem!
Jiminy Jack Christmas! Nice lock-on Big Dog! That was all you, that was all you! We're pullin' your ass out! You're gonna be doing this thing without a wetsuit and a beret and glasses on, if I have my way.
The entirety of the Top 25 episode, where they list their favorite things about the show, when it isn't being awesome. Namely, thing #7, which is Jamie Hyneman. At one point, it compares him to a walrus while swimming. Also, #3 is Adam and Tory hurting themselves...
What really sold the Jamie segment was Grant's comment at the end, after a string of "impressions" of Jamie that consisted of Grant holding his fingers up in front of his face to simulate a mustache in various moods:
Adam makes an offhand remark during the above clip: "This doesn't usually happen to me; it happens to Jamie". This is actually a Call Back to a previous behind-the-scenes special (MythBusters Revealed), which features over a minute's worth of clips of Jamie getting tongue-tied. Including one during the interview for the special.
The special opens with a mock Avengers Assemble introduction, with Adam dropping in from the ceiling in mountain climbing gear. He then proceeds to attempt to follow Kari, Tory and Grant as they walk off-screen to start compiling moments, only to get part way before he reaches the end of his rope and gets pulled back.
In "Walking on Water":
When they were testing the mizugumo, we get this gem of a line.
Adam: COME, SILENT WALRUS! Let us storm the castle! I will don my safety gear! Jamie: ...
Even funnier considering the fact that Adam's mouth is covered up, and he is busily punctuating his words with Power Rangers-esque head jerks.
Adam puts on a pair of shoes that the narrator describes as looking like "container ships." As Adam tries to step off the edge of the pool into the water, he immediately loses his balance and falls face-first into the water. As Jamie looks on, Adam simply says; "If I had any dignity, that would have been humiliating."
When Grant and Tory went into the water in the Jaws special, we find out Grant doesn't like fish touching him. This results in him screaming "Help!" in a Cajun accent, which sounds like "HAYELP!!!"
Kari's taunting certainly didn't help:
Kari: It's really realistic, almost like you're scared!
And then proceeds to shriek at the top of his lungs, "SOMETHING JUST TOUCHED ME."
Before getting into the water with sharks, this exchange.
Tory: I hope they like sushi! Grant: Oh, I hope they like Italian!
And after the first test, Kari tells them they need to go in the water again, switching roles to remove the variable of who the swimmers were:
Grant: Oh, damn you and your science!
The boys recently did the cold open of the Late Late Show with Craig Ferguson. Adam was in his spacesuit get-up, and both had to hold up cue cards for their lines in the song. But Jamie is just... Jamie. And for the most part, stands there totally deadpan the whole time, which makes it frackin' hilarious.
Ordinarily, Jamie isn't much of a comedian, so it means a lot at that at the end of "Phone Book Friction," he's standing next to two phone books that have been torn apart by tanks and says "I just wanted to make a phone call"...and the camera crew cracks up laughing.
Adam and Jamie test taking candy from a baby and losing to one.
At the end of the last test, Adam asks the oldest baby for a high-five. She gives him one. (Sure, it doesn't sound like much, but picture a one-and-a-half-year old giving a pretty solid high-five for someone of that age. It really is the little things sometimes.)
Adam attempting to walk on hot coals without knowing the technique.
Adam (calling his wife): "Hello honey, I walked on hot coals today and I burned the hell out of my feet."
From one of the early seasons while testing how to beat the breathalizer, they had to have a few drinks first to get into the right range. In the extended cut of the episode, Adam's first breath test after proclaiming himself "lit" was... a .03. (.08 is legally drunk.)
Adam: I guess I'm a cheap date!
Jamie: Adam, the police officer said you need to drink more. Adam: You know, my Doctor was also telling me that I'm not getting enough tarůso, I need to start smoking again!
Adam: So we've had 13 drinks over 3 hours. I know I'm drunk, but I can't even remotely tell that you're drunk. It's kind of annoying. I want to see you put a lampshade on your head or something. Jamie: Sorry, bub!
Police Officer: [to Adam] He's doing fine. You just sit over there and be quiet. It's rough enough to have one of you here. But having two... Adam: [laughing] Of course I'm causing trouble.
When Adam and Jamie built their arrow "machine gun," it had... problems. Lots of problems. Eventually, during one of its many, many breakdowns, Adam just gives up:
From the Cold Feet Myth, when Kari examines her meal:
"Why is it that I am a grown woman, and boys are still trying to make me eat bugs?"
The Compact Compact revisit gives us this gem. Jamie wanted to use more breakaway rope than Adam. Adam got his way, and sure enough, the rope breaks prematurely.
Jamie: The weakest link in the chain was the breakaway rope and that's what we wanted it to be. Subtitle: The weakest link in the chain was Adam! Jamie: Now exactly how strong does that have to be, it's really kind of... it's a guess. Subtitle: Exactly how strong it needed to be was what I said it was. Jamie: And we guessed wrong. Subtitle: And Adam guessed wrong. Jamie: Uh... Subtitle: %$#!. Jamie: ...We need to put more rope on there.
Adam is getting frustrated with the slow progression of the "lift a sunken boat with ping pong balls" myth. Jamie's advice to him on calming down is gold.
Jamie: We just tested it. It works. Go have a cookie.
In MythBusters Revealed, Jamie reveals his comment has to do with his belief that Adam sometimes gets so involved with his builds he Forgets to Eat, and in these cases Adam gets a bit cranky due to low blood sugar. A quick-fix for this issue is for Adam to literally go have a cookie.
The uncut version shows that the progression was slowed further because of an otter that swam into the sunken boat and stole one of the ping pong balls.
Adam: I'm a sad monkey.
From the same myth, the torpedo flying into the sky. Test 1 was particularly hilarious, as it flew into the sky to a ridiculous height and did a few loops.
During the "Blue Ice from a Plane" myth, when the (now red for visual ease) ice hits the ground, a nearby bird is visibly startled by the impact and starts flying away. It's subtle and very possible to miss completely, but it's hilarious.
Then there's the bit in the second James Bond special where three Adams sing "fire in the hole", prompting the Narrator to comment, "...Okay, Adam, now you're just really taking the barbershop thing too far. Just press the detonation button, will ya?"
From the Pirate Myths, we have a tumbleweed inexplicably showing up as Adam is grinding down a cannonball to fit into the cannon, and Tory digging a hole as the others pretend they're in a nature documentary.
In the Pottery Record myth, Tory has a ludicrous leadfoot... on a pottery wheel. Yes, his first instinct when he comes across a pedal-powered pottery wheel is to floor it. It sends clay flying across the workshop. His first pot ends up being very small as a result.
Tory nonchalantly flings one of the resin-laminated paper squares off to the side. It embeds itself in a piece of cardboard. Tory then just breaks down. His reaction is almost as funny as the unexpected landing!
In the "Mirror Lights" myth, Jamie makes the darkened room the brightest it gets in the whole myth. How? By stepping into the beams of light cast by the mirrors... and letting it bounce off his white shirt. Jamie is literally glowing as the beams scatter off his starched white shirt. Adam loses it.
Jamie: And you said I didn't know how to light up a room. Adam: I stand corrected.
Adam is failing to make a hovercraft, and he's already gone over his budget twice, so he's feeling a little down. So the cameraman tries to comfort him:
Adam: I'm out, I'm out of ideas, just this second. (Laughs when the cameraman pats his shoulder) When a pat comes from the cameraman, you know it's really, really bad.
Grant is showing Adam and Jamie how to fly his model airplane as part of the "airplane on a conveyor belt" myth. Jamie is uncomfortable:
Jamie: I don't know if I can handle this, actually. We're using this particular item the way that it was intended.
Adam loves doing a fake Nature Documentary voice-over whenever he's near the camera (i.e. the Wild Hyneman) and Jamie is in the distance. These are funny enough, but one time Jamie turns around in the middle of one of these and outright says "Is he doing his David Attenborough thing again?" Adam loses it.
In the "Walk in a straight line blindfolded" episode:
At the beginning, Adam is blindfolded and we get this exchange:
Adam: You ever work on something, and it's not going the way you want it to, and you feel like you're just...going around in circles? Jamie: I know exactly what you mean. *holds up a sign that says "Every day I have to work with him"*
At the end of the opening segment, Jamie holds up a sign that says "Bye" then walks away, and Adam doesn't notice and just keeps talking.
At the end of the episode, the roles are reversed; Jamie's blindfolded and Adam's holding up the signs. As Jamie starts talking, Adam holds up a sign saying "Here we go...", and when Jamie starts lamenting on the fact that they couldn't figure out why the myth was confirmed, Adam's sign reads "Always complaining".
The simple fact that the episode ends with two grown men lost in the woods with big plastic buckets on their heads. Apparently this is an actual inclement weather simulation tactic used by professionals.
The beginning of the "James Bond Special." Within about one minute we see Jamie in a tuxedo; Kari doing an over-the-top Bond Girl voice; Adam wearing scar makeup (and looking like a genuine Bond villain); Grant trying (and failing) to look menacing; and Jamie introducing himself as "Hyneman. James Hyneman." before shooting at the camera a la the 007 films.
At the end of the small-scale test for the "Rocket Man" myth, Kari, Grant, and Tory are standing on a platform with several missiles as Grant lowers it into the ground. Realizing how much they look like supervillains, Grant starts laughing maniacally as they drop out of view, with Kari adding in a few of her own laughs. Tory's reaction to all of this: a simple shrug as he looks at the camera.
Basically, any time Tory ends up playing the Straight Man to the other two members of the Build Team, since it generally means the other two are being very over-the-top, on top of it being a prime Out-of-Character Moment. Kari and Scottie's antics partway through the "Talking to Plants" myth is a prime example.
"Robo-Turkey" in the Bird Car Tip myth. Grant rigs up a frozen turkey with robotics to make its tiny, featherless wings flap and its legs rumble. It's disturbing, but it's also a naked cybernetically enhanced turkey flopping around on the roof of a car.
Later, when they finally manage to make the car tip over, the 80+ frozen Cornish game hens Kari threw on the hood of the car go flying off at breakneck speed as the car tumbles down the ramp. It's so utterly ludicrous it must be seen to be believed.
In the Confederate Rocket myth, Grant is attempting to talk about nitrous oxide gas...while in the presence of an apparatus that's slowly creating the stuff. Given that the common term for nitrous oxide is "laughing gas", I think youcan guesswhat ensues.
The coffee creamer fireball, a classic Mass "Oh, Crap!" moment for Grant, Kari and Tory.
During the "Mind Control Chip" myth, Adam had to learn how to use a studfinder in its various modes. Jamie placed a series of studs, metal tubes, wires, and microchips behind a wall in oddball configurations. Adam was mostly able to find the larger items behind the wall (not the microchips, though), but one area proved a bit of a blind spot. When Adam went around to the other side of the wall, he saw what he'd missed: A series of metal wires twisted into the words "Adam is a spasm". Adam lost it.
In the Duct Tape Island episode:
In a complete role-reversal, Adam is the one who finds and creates their shelter (complete with furniture and a homemade chess set) while Jamie creates a surfboard out of duct tape and tries to use it. Too bad Jamie doesn't know how to surf...
At the end of the episode, after escaping from the island and a few congratulatory minutes...
Jamie "Adam. It's the same island." Adam *Face Palm*
If you look closely, you can see that Jaime used some Duct Tape to patch the hole in his shirt.
During the Catching a Sword myth from the ninja special, Kari, Tory, and Grant are doing some force-testing. Then, all of a sudden, Adam comes running in out of nowhere, shouts "YOUR KUNG FU IS NO GOOD!" and smacks Tory in the face.
In episode 213: Pingpong rescue, after they bust the myth that balloons are able to lift a 40 pound child off the ground, instead of the team saying that the myth is busted, they have the kid they used in the episode jumping on the "busted" sign repeatedly saying "Busted-Busted-Busted!" both hilarious and adorable.
In the "Confederate Steam Machine Gun" episode, Adam has finished his piece of the rig: a reloading mechanism for the machine gun. He then launches into a bizzare explanation (with a hilariously bad French accent and complete with subtitles) of the rig, which finally culminates in the subtitles saying "...I think I'm losing my marbles," before flashing "???" as Adam finishes the sequence with what amounts to complete nonsense. Granted, Adam is a funny man regardless, but...
If you actually do listen, it's not merely nonsense, it's True Art Is Incomprehensible taken to the next level, acting like a French artist describing a surrealistic work of art in the most obtuse and hammy way possible. Which only works to make it funnier.
Square wheels. Specifically, square wheels on a huge truck. Somehow, watching it go clunk-clunk-clunk-clunk down the road at a progressive pace is utterly hilarious.
While testing Never Bring a Knife to a Gun Fight, Jamie runs screaming at Adam holding a foam knife...only to trip, fall on his face and skid the rest of the way to where Adam was standing. Naturally, it was caught on high-speed as well.
Grant looking into his blowgun and accidentally shining the laser sight into his eyes.
From the same myth, Kari revealing she'd concealed a copper tube inside her blowgun, which was cheating. Specifically, Tory and Grant's reaction. Kari then points out that Grant at least didn't have much room to complain, considering he'd used a laser sight.
Tory, Grant and Kari attempting to build a jet-engined Go-Kart - the myth said it went at crazy speed, yet when they did get it to work, it only went 5 mph! This results in perhaps the slowest fence collision in MythBusters history.
Tory, Grant, and Kari are testing whether an all-right turn route is more efficient. As they are in San Francisco, this happens:
Kari: Oh my god, we're going to Lombard Street! Tory: Ah, I love a challenge! Kari: That's the crookedest street in the city, possibly the world! Grant: No, that's Wall Street.
The "No Pain, No Gain" episode features (as might be expected) several myths about pain. During the introduction to the segment, Jamie chips in:
In the 2012 Halloween special, there's a quick shot that sums up the entire show: In a dark room, Jamie lights a match to illuminate his face and says...
Jamie: What scares Adam? I do.
In the Alaskan Cabin Fever myth, Adam and Jamie are forced to endure isolation, loneliness, and dreary, dull, uninspired conditions for days on end. These men are both highly active, almost over-creative thinkers, so it's clear that this won't end well. It comes to a head when Kari decides to mess with them by including an Abominable Snowman in the test to peer in through the windows of their cabins. Jamie being Jamie, he simply states "Oh great, we've got a Yeti outside," with his usual tone of mild annoyance. Adam's response is much more animated and hilarious: he freaks out and hides in the bathroom, fearfully peering out past the doorjamb to make sure it's gone.
Another hilarious moment was Adam describing a dream he had that he was in a plane slowly crashing in the streets of San Francisco with Adam in the cockpit until (in-dream) said this to the passengers.
Adam: Listen, I don't think this is a real plane crash 'cause I happened to notice that I'm not wearing any pants and whenever I'm not wearing any pants, it's probably a dream.
Driving in Heels. Jamie Hyneman in a Nomex race suit and 4 inch bright red high heels. Need I say more?
Question: Was it hard to show restraint with [the Dynamite Ax myth]? Weren't you itching to just add 100 pounds of explosives just to see what happens? Kari: What, you think we're just crazy, that we're just- Tory (simultaneously):"Yes."
Jamie giggling like a child while being propelled around the workshop on rollerskates by his prototype for the hovercraft is gold.
After a full episode of building up to re-testing the JATO rocket car myth, they finally get to the actual test... and right as the car approaches the ramp, it abruptly explodes, shocking everyone. Obviously nobody on the scene expected it, and from the set-up, neither does anyone watching for the first time.
One involving Frank Doyle: during the Exploding Pants myth, he was supervising Tory while Tory was preparing the chemicals that were going to be tested.
During the second Alaskan myths special, there's a flashback of the first special's snowplow myths and how their inflatable doll crash-test-dummies both were popped in the testing, and it shows Tory grabbing the female one to extremely over-the-top tragic music in slow motion while he attempts CPR on the doll, with a squeak-toy sound effect going off every time he pressed on her "heart".
Any episode involving uncooperative animals.
The entire "Fainting Goats," myth. First a goat accidentally kicks Tory in the nuts. Then Kari "gets out the big guns" and "flashes" the goats, which is hilarious because she appears to be seriously doing it in an attempt to make male goats faint. The only one it "works" on is Tory. For their last attempt, they dress up as farm animals as a disguise... and finally get some goats to faint. Meanwhile, the camera crew are causing goats to faint left and right. Kari and Tory are not amused.
When testing the solutions for skunk stench, they tried to make one spray them by scare-jumping on it and trying to surprise it...but the skunk didn't pay them attention. They asked for another skunk, and this one ignored them too. So then they resorted to a chemical substitute...which still was problematic, as it wore off more quickly than the genuine skunk spray, so they had to get yet another skunk, which finally sprayed them (but only after a great deal more rigmarole).
They had similar problems when testing if the quacking of ducks didn't have echo. Trying everything on them to make them quack had no effect, leading to Jamie's famous "Quack, damn you!" quote. Eventually, the ducks quacked without any provocation when they brought them back together. Apparently ducks don't quack when there aren't any other ducks to quack to.
At the very end of the episode, after all the testing was finished, they brought the ducks to a dock. Upon seeing the water, the two ducks begin quacking with more enthusiasm than they had at any point during testing.
In the myth involving caimans, Kari, Tory and Grant tried to provoke them into a quick attack, but again the animals didn't cooperate. It's especially funny when they were using a chicken on one, as the reptile slowly turned its head to look at it, then just as slowly it gave a couple of steps towards it and stopped again, like it was thinking "not worth the effort''. It got so bad that Kari, Tory and Grant threw themselves to them and, as expected, that didn't work.
In the episode where they were testing the fan theory that Jack and Rose in Titanic could have both survived, this is how Adam introduced their guest.
Adam: This is James friggin' Cameron.
Cameron: I am indeed James friggin' Cameron.
After the Drain Disaster myth had been tested, and eventually confirmed, Adam stands with a manhole cover with the numeral 2 on it. What Adam says is golden:
J.D. Nelson in the YouTube Special, commenting that, if the million-matchhead cannon were to go off while they were standing next to it, it would be "time to de-ass the area with a quickness."
During the zombie episode, the build team is trying to figure out ways to trick and sneak past a zombie horde. Kari is the first one to try her plan—shoving Tory into a wheelchair, duct taping him to it, and shoving him to the zombies as bait. And it works!
Revisiting an old myth based on a Mr. Bean episode and a The Far Side comic, the MythBusters attempt to paint an entire room by virtue of explosives immersed in paint. Adam cheats the system slightly by painting with explosives, IE, art pieces instead of simply going for wall coverage. The contraption he builds is already good for a giggle in and of itself, but it's his comment upon seeing the results of the slow-motion footage that sells it.
The Jamie's House of Bent Barrels advertisement during "Bullet Baloney". Jamie using a southern drawl makes this all the more hilarious.
Jamie: We got a gun that will do whatever you want. [points curved gun barrel upward] Duck huntin'. [points curved gun barrel downward] Fishin'. Heck, it'll shoot things you can't even see. Only $19.95. Curved ammo sold separately.
Adam and Jamie's complete and utter failure at trying to herd cats. Getting all the cats to react to the same thing at the same time is pretty much impossible, some of them just refused to react or move at all, and even if the boys succeeded in getting them in the pen they kept walking out. They even tried an actual herding dog and failed. By the end of it the poor dog was cowering behind its handler.
Tory, Kari and Grant trying to catch greased pigs. Then Tory and Grant come up with overly-elaborate devices that are supposed to make the pigs easier to catch. Kari ends up beating them both with a pair of gloves with fur on them.
During the original Archimedes Death Ray build, Jamie finds a flaw with the design.
Jamie: Our Death Ray...doesn't seem to be working. I'm standing right in it, and...I'm not dead yet.
When the Build Team tested self-hypnosis, they called in Adam to test for his fear of bees. One test later, Tory gives him the self-hypnosis CD.
Tory: Alright then. This is the CD that you're gonna listen to for a week, and this will help you get over your fear of bees. Adam: Did you guys make this? Tory: We ordered it online. So, you're in good hands! It's the professionals! Adam: I didn't wanna hear you going "DUDE, IT'S TOTALLY OK! IT'S TOTALLY OK!"
During the escape slide parachute myth, Adam and Grant find the survival ration kit to the escape raft they're using... which is extremely out of date. Hilarity ensues as they try out the various things inside, such as a green-colored liquid (which Grant drinks and Adam thinks is alien blood), expired bandages, and coffee-flavored stimulants, which Grant and Adam jokingly say they have an addiction for afterwards. To quote Jamie:
Jamie: It's just like Christmas!
In the Killer Tissue Box episode, one of the "alternative" objects they use on a ballistics gel rectangle is a hatchet. As the Narrator says, it winds up looking like "something from a b-grade slasher film". After getting over his hysterics, Adam delivers the coup de grace:
Adam's pirate accent never fails to give Jamie the giggles. At best, he can be seen to be barely keeping it together, and at worse, he's pretty much a goner.
In Fireball Stun Gun, Kari learns that, when faced with runaway fireworks, she will use a co-worker as a human shield.
In the attraction episode, one myth they're testing is whether people will become dumber when faced with members of the opposite sex. Adam builds the test area...and proceeds to lock himself in by closing the door when the doorknob wasn't installed yet. Jamie has to toss over a drill and a screwdriver so Adam can pry the door open.
The first myth of the traffic episode. The rage quit was so potent it mirrored the actual event in Real Life.
During the episode dedicated to The Walking Dead, Kari, Grant and Tory test if its impossible to avoid a horde of zombies by running through them and are devising ways to distract the zombies. Kari's method? She duct tapes Tory to a wheelchair and pushes him into the crowd of zombies.
