S1E01 "New Family, Part 1": While searching the tunnels to make sure there aren't any more eggs, Nick gets Randy to find info if there were any new power or gas outages, which Hicks learns "find info" as Randy hacking Con Ed's satellites. Hicks asks who Randy is, Nick jokes back with "I'd Tell You, but Then I'd Have to Kill You."
There is something very funny about a juvenile Godzilla getting his front half stuck in the barrel-trap that the group sets up, when they were expecting a more human-sized Godzilla.
When the team flee in terror from Godzilla and hide inside their headquarters, not knowing that Godzilla had imprinted on Nick as his dad and won't hurt them, Godzilla reacts as a faithful dog waiting to be let in would: he scratches at the door, turns around a couple of times, and lays down with a sad whine. Daaawww....
Nick arguing with Elsie on the decision to keep Zilla, Jr. alive.
Nick: You're a paleontologist, Elsie. Why the rush to destroy your only living specimen? Elsie: Common sense? Mendel: Past experience? Randy: 23 billion in property damage from his old man? note Made all the more funny when taking this video tallying up the damage costs into consideration. Nick:*glare* Randy: What? No, uh- Well, I'm just sayin'...
S1E04 "Talkin' Trash": During Godzilla's fight against the Nanotech Creature:
Felix Hoenikker: I thought the army destroyed Godzilla? Mayor Ebert: It's NewJersey's problem now.
Randy replacing N.I.G.E.L.'s voice with Mendel's mother's voice.
S1E06 "Cat and Mouse": One of the out-of-town hunters tries to patronize Monique, of all people:
Bill: Don't you worry your pretty little head, miss; we can handle it.
S1E11 "DeadLoch": After Monique performs mouth-to-mouth on Randy, he pretends to still be unconscious to get one more "kiss" from her.
Monique: I should throw the little one back, no?
Poor Randy being subjected to the bagpipes.
S1E18 "Web Site": Mendel's skin turns orange due to an unexpected reaction to a lotion with bug-repellant in it that Randy had lent to him.
After Nick points out that female black widows only eat their male mates when being in enclosed captivity for long periods of time, Randy has a "Hey, wait a minute" thinking look. note A bit of Truth in Television in that some hypothesize it's the stress of being held in captivity that causes female spiders - and some species of insects, like mantises - to eat the males during reproduction.
When Mendel thinks his sonic signaler is a success after getting Godzilla to roar, he gets splashed by a large wave when the Big Guy belly flops back into the water.
S1E20 "Trust No One": As Godzilla tries out the seaweed-based fish substitute Nick had whipped up and before he spits it back out, N.I.G.E.L. reports in to a familiar tune.
Mendel: What kind of twisted mind would intentionally make such a bizarre lifeform? Randy: Let's ask your parents.
Elsie goes into scientific detail on the effect of nitric acid should have on the DNA Mimic, prompting Randy to snark about her needing subtitles. She sums it up on knowing a way on how to kill the Mimic.
Randy claims insult when the team catches the DNA Mimic messing with N.I.G.E.L.
"Hey, it can't do that! Only I can do that!"
S2E01 "Future Shock": Future!Mendel gives his futuristic rifle to Nick and tells Nick "Just make sure [my past self] don't barbecue any of you by mistake." Back in the present, when the team are preparing to go after Insley, Mendel accidentally discharges the rifle and damages a counter top just as Monique is walking by, who simply shakes her head.
S2E02 "Cash of the Titans": Randy trying his badly pronounced French on Monique.
S2E03 "S.C.A.L.E": Audrey interviews the team after the events of S.C.A.L.E.'s little jaunt through Monster Island. When it's Mendel's turn...
Audrey: At that point, Dr. Craven, were you frightened? Mendel: I am a professional. I am never - ever - frightened. *N.I.G.E.L. promptly turns his head to look at him as if to say "Oh, really?"* *cut to footage of Mendel ducking just under the Giant Bat's feet, Animal panning the camera down to show Mendel with hands covering head, whimpering and crying for his mother*
When Randy activates N.I.G.E.L. to send out a distress call, the yellow bot starts rapping hip-hop (which Randy later somewhat denies having any hand in), prompting two of S.C.A.L.E.'s members to shoot him and give his head to Mendel.
Monique's response to Audrey's request for an interview:
Audrey: ...Ms. Dupre? *A ninja star flies out of Monique's room, coming within inches of Audrey's head.*
S2E07 "What a Long, Strange Trip It's Been": When it looks like Godzilla's about to sneeze, Monique asks Nick what they should do, as they were in his nose. Nick simply shrugs.
Mendel being covered by the Mutant Bacillus's dangerous slime is par for the course. The truly Funny Moment is when Godzilla sneezes a second time (the first time expelled out Nick, Monique, and N.I.G.E.L.), Mendel winds up being covered in his nasal mucus (AKA snot), much like Lex being covered in a Brachiosaurus's snot in Jurassic Park. Like her brother Timmy yelling "God bless you!", Randy yells out "Gesundheit!". Godzilla even wipes his nose.
S2E08 "Wedding Bells Blew": Randy reprogramming N.I.G.E.L. to quote lines a'la the Bard of Avon.
When Nick is telling Godzilla to "stay", he was talking to Elsie on his cell phone at the same time and she thinks he's telling her to keep staying with her family.
S2E09 "Metamorphosis": After getting $5 million dollars anonymously, the team has trouble deciding what to do with it throughout the episode until Monique finally decides to become their financial handler at the end. And then Randy asks her about his "allowance".
S2E11 "The Twister": Randy's epic "Noooooo!" on loosing his chance to win the radio-sponsored vacation trip to Jamaica, which Mendel inadvertently won when he had intended to call the pharmacy.
S2E15 "Underground Movement": Randy and Mendel after surviving their first night in the woods.
S2E17 "Vision": Randy read an email that was intended for Mendel and assumed that a fatal virus mentioned in the email meant that Mendel was dying, so he acts nice throughout the episode, driving Mendel crazy. In the end, the "fatal virus" email was just about an Egyptian mummy autopsy that Mendel was doing for Elsie.
When Godzilla is fighting mutant hummingbirds, one can't help but laugh when he makes a lucky shot at one of them with his tail.
