Hugh: Hey there, Jib-Jab, I was just in the neighborhood, and I wanted to have a little chitchat with you about this, uh, "pants" business. (dramatic music swells) Y'know, son, believe it or not, there was a time when I myself used to leave my pants on the floor. And then one day, I...I picked them up! And, well, the rest is history, son! Speaking of history, just think: what if our Founding Fathers had left their pants on the floor? What if Attila the Hun hadn't picked up his pants? What about Luke Skywalker? I tell ya, the Force was with that guy's pants! (beat) I'm glad I've cleared this up for you, son. (sniffs) Goodbye. (beat) Whoopsy-daisy, barn door's open! (zips up his pants)
Practically everything Hugh says counts as a CMOF.
When they're all at each other's throats in "Battle of the Bands", except Carl, who's just yelling "DRUM SOLOOOO" over and over again in a bad Liverpudlian accent.
The opening of "Lady Sings the News" has Jimmy switching the images of the local news anchor's and weather-girl's heads with those of Sheen and Carl, respectively. Carl discovers what happens on the screen when he spins around in Jimmy's room...
Carl-head-on-weathergirl: Come on, Anchorman! Spin your head with me!
After Jimmy admits he's been using advanced bats and mitts he gives his team a Rousing Speech saying they can win without them, and the match still ends with them having gotten 0 runs.
At the end they go see a Godzillaexpy, and when Sheen sees that it's laughably small it breathes fire in his face. He then asks Jimmy if he knows the Japanese word for "ambulance".
The entirety of "Grumpy Young Men", though some highlights include:
Sheen staring at the standee for an M-rated game in an attempt to spite the cashier after he throws the trio out, after which the cashier throws an ice cream cone at him.
Goddard's reaction to seeing Old!Jimmy, which is to let out a stock horror movie scream.
Old!Sheen complaining about how kids today wear their pants.
Old!Jimmy being carried across the street against his will.
Even Cindy and Libby were impressed with Hugh's determination to get Old!Jimmy across the street.
Old!Jimmy convincing Old!Carl and Sheen to step through the Chronotron with offers of prune whip on the other side, followed by them trying to squeeze through and Goddard pushing them through the gate with seconds to spare.
Carl eating Jimmy's bowl of experimental truth serum and promptly spouting out deranged secrets, including liking Jimmy's mom and not really believing in Ultra Lord.
Sheen: (covering his ears) LALALALA LALALA!
"And the gold under our lawn to use in case Dad decides to give all our money to telemarketers! ...Again."
The Nanobot duo are very amusing. Some of their highlights in their episodes...
Nanobot 01: (knocks on Jimmy's door to the lab) Telegram.
Carl: Like I'm gonna fall for that.
Nanobot 02: Llamagram.
Carl: Llamagram?! Oh boy! (opens the door... gets deleted)
"And we want our cookie back!" (pulls out a plunger)
After the Nanobots first get into the saucer transport:
Nanobot 01: (Sees Nanobot 02 glaring at him) What?
Nanobot 02: Your chair is bigger than mine.
The above becomes a brick joke later on once the Nanobots enter their saucer in another episode:
Nanobot 02: I call captain's chair!
Nanobot 01: Over my dead relays! (Beats up 02, throws him into other chair)
In "Sorry, Wrong Era," Carl begins dancing calypso and Jimmy stares in shock before briefly giving an Aside Glance to the viewers.
In "The Tomorrow Boys", heavy metal rock band Graystar is about to play at Retroville. Upon the future Cop-Bot seeing them:
Cop-Bot: Graystar! My favorite classic oldies band!
"Jimmy For President" has Mrs. Fowl listing off the transgressions of the candidates as bribery, blackmail & MURDER!, causing all the students in the auditorium chairs to scream in horror. Mrs. Fowl corrects herself, stating that the last one wasn't murder, but piloting a blimp on school property without a permit.
Sheen's attempt to read hieroglyphics. It starts off fairly convincing, shocking the others, then quickly dissolves into hilarious nonsense.
This exchange before they watch the video on Egypt:
Ms. Fowl: Butch, would you hit the lights, please?
Butch: Sure thing, teach! (Pulls out a slingshot, shoots at the light, destroying it)
Ms. Fowl:(Pinching the bridge of her nose, understandably annoyed) Thank you.
When Libby commands the mummies to bow to her, each of them do it in a different fashion: The first one bows gracefully, the second one does so awkwardly, the last one just falls forward.
Hugh pretending to be Gollum in "Lights, Camera, Danger!"
In the same episode, Jimmy tries to get inspiration for his movie script by watching various old movies at rapid-fire speed. Eventually, the series of movie quotes end with "Gotta blast!", followed by Jimmy giving a smug Aside Glance to the camera.
Sheen's script, which he "wrote" by taping pieces of the phone book together.
"I call it Attack of the People Named Frank Johnson!"
