"S&Ls are unkillable! Ever see It's A Wonderful Life? Even that Bailey bastard couldn't screw it up!"
Peanut's explanation (in Japanese) that it's considered customary in American culture to blow something up once a business deal has concluded. And then he fires a bazooka at Phil, leading to the above-mentioned dislocation.
The episode "The Devlin Made Me Do It", through and through, comedy gold. Especially Devlin's constant crashes and amusing injuries.
Also of note, the And Knowing Is Half the Battle message on one of Devlin's tapes that Harvey was using for evidence is ruined by Deviln himself pointing out how riding without a helmet(the exact thing the PSA is trying to tell kids not to do) is cool, talking about using a condom and hitting on the young girl in the video.... which leads to Harvey frantically trying to stop the tape while blocking the screen.
Devlin's how-to tapes, culminating with "How to Jump Over a Ravine On a Bicycle Comma Bobby".
Bobby, the kid who got injured imitating Devlin, has some really hilarious moments too due to the sheer amount of crap he's put through, such as his lawyer Freezoid accidently leaving him in the middle of the street while talking to Birdman, causing him to get hit by a truck, and Birdman tipping over Bobby's wheelchair because Peanut told him he saw Bobby moving so he must be faking his injuries.
When Reducto has one of the members of Shoyu Weenie on the stand, she answers his question in a slow, breathy voice in Japanese. Pretty much every man in the courtroom turns to her with a shocked and/or aroused look on their faces and dropped jaws, including a guy carving a wood statue with a chainsaw and a clown making a balloon animal. It helps that the translation of what she was saying is roughly "My name is Seiko, I like that song, it's a pretty song."
The Teaser for "Shaggy Busted", where a (live-action) cop pulls over Shaggy and Scooby.
The live-action interrogation clip from "Death by Chocolate", where a pair of cops get aggressive at a man in a Boo-Boo costume.
In "SPF", Harvey gets paranoid of the sun and wears protective coverings, telling Peanut that the sun can kill him. Peanut responds by quoting a parody of the NRA slogan "People with suns kill people" whilst polishing a gun pointing right at him.
The cut to an old 1960s clip of Birdman receiving his powers from the sunlight, which delves into an orgasmic reaction.
Harvey complaining about Potamus parking his blimp/arc across two spaces, followed by him shouting "Hippo!" at Potamus, after which a sex doll pokes out of his trunk.
Mentok's battle with Shadow the Brain Thief in "Harvey's Civvy." During the trial, Mentok gets so fed up with Shado's ripoff of his power, that they veer off into a sort of wizard's duel, trying to out-do each other. This troper lost it when Mentok began making the stone-faced security guard do a Russian dance.
Because I'm Mentok! The MILF Spu-*claps hand across mouth*
"Blackwatch Plaid," fullstop—the episode where Secret Squirrel is being sued for flashing. Half due to the hilarious use of the character Secret Squirrel, and half due to Phil Sebben's hidden camera footage showing Harvey and his co-workers in live action (including footage of live-action Harvey frolicking around Atlanta and the Turner Mansion's front lawn), and climaxing with the combination of these two plot lines.
Its even better when everyone in the court room starts pointing at him when he grows.
Dr Reducto is a virtual fountain of these, especially him freaking out when he tries shrinking Grape Ape and Grape Ape just pumps himself back to normal size again.
Reducto: *running around screaming* I HAVE MET THE UNSHRINKABLE!!
His reaction to meeting Inch High, Private Eye? Some kind of weird obsession due to Inch being "so perfectly miniature" that Reducto doesnt know if he should destroy him or love him.
Reducto: I hate him! *Harvey slaps him* I love him! *slap* I hate him! *slap* I love him! *slap* I hate him AND love him!! *starts to tear up*
After encountering Atom Ant, Reducto goes insane, and tries to form an alliance with Inch to destroy him, because he's smaller than either of them. Inch, who doesnt have Reducto's bizarre obsession, doesnt really understand the problem.
And of course there's the Jetson family struggling to reach Birdman's desk without conveyor belts, and taking all day to crawl a few feet.
The reason the Jetsons are in the past? They want to sue the present day for causing global warming in the future. Turns out that the reason they all live on those poles is because of massive flooding.
Oh, and the real kicker - Harvey is actually George's ancestor. When Harvey takes this as a sign that he will finally get laid at some point, George just states that "there are other ways".
"The Dabba Don", while Fred Flintstone is on trial:
Dinosaur: (on witness stand) The guy's a pig, a neanderthal. Fred Flintstone: You're DEAD to me, can opener!
Harvey just doesnt seem to grasp the whole "mobster" thing, so he keeps waking up with the heads of different cartoon characters in his bed, including Quickdraw Mc Graw and The Gleep.
Harvey: AAAAAHHHHH!!!! Ew, Gleep juice!
Peanut keeps trying to suck up to Freddy, hoping to be accepted into the mob.
The ending, which is a parody of the climax to The Godfather, which shows Mr Slade being forced to sign over the quarry, the bird can opener being assassinated, and Pebbles baptism.
The people from Hoot n Holler, the setting of the cartoon Ricochet Rabbit, keeps shooting into the air and yelling whenever anyone says the name of the town.
