Cosgrove is telling Freakazoid that he needs to go into the sewers to chase down Cobra Queen, but Freakazoid absolutely won't do it because they smell like poo gas. Then an immediate Gilligan Cut to the sewers where ... Freakazoid is not present. Then another cut to his apartment where he's watching TV and says "See? I said I wouldn't go."
Or how about when Brain, Wakko, and Freakazoid started arguing over who Spielberg likes the best:—> (cut shot to office) Spielberg: Who are you people?
Cosgrove's pretty much a Crowning Dude of Funny. "Hey Freakazoid, wanna go watch a bear ride a motorcycle?"
And is followed by "Pigs are smarter than bears, but they can't ride motorcycles."
The entire episode in which the heroes (And several villains including Cand-I mean...You-Know-Who) crash land on a deserted island where a Mad Scientist (Played by none other than Tim Curry) has created an army of half-human half-orangutan monsters.
Narrator: "Freakazoid!", in stereo where available. And where not available, it's not in stereo. There's nothing we can do about that, so don't blame us. We have no control over it. Call your cable company if there's some sort of problem, or the local broadcaster, but if THEY aren't giving you stereo and YOU want stereo, that's your problem, NOT ours, DON'T BUG US!!! Blame your congressman, or NEWT GINGRICH, LIKE I'M SURE HE'D CARE!!!!!!!HA!!!!!!!!! BUT, ''WE' don't want to get any letters, UNDERSTAND?!?!?! GOOD.
When Gutierrez tries to affect Freakazoid with kryptonite to no avail because that's Superman's weakness. Then he tries the color yellow but that's the Green Lantern's. Next, he tries water, but that's the Wicked Witch. Finally, he just asks Freakazoid what his weakness is.
When Dr. Mystico says they'll be plenty of time for explanations, Freakzoid points out the show's almost over. At which point Mystico starts screaming at them for wasting so much time on the plane before recomposing himself.
In The Chip, one of the first things Freakazoid does upon...coming into being is zoom all the way to Tibet where a monk is raking the ground.
Freakazoid: WILL YOU PLEASE STOP THAT INFERNAL RAKING?! IT'S DRIVING ME CRAZY, SHEESH!!
And in part II, just before defeating Gutierrez, Freakazoid zips back to that monk to apologize.
Monk: It is all right, my son.
At the end of Mo-Ron's debut episode, he finally remembers the message he was supposed to deliver; A comet's going to hit the area! As everyone else panics and flees...
Freakazoid:Now he tells us!
In general, all his segments in that episode are stupidly funny, in a Kung Pow sort of way.
The Lord Bravery segments also have some funny ones. Such as the bit where Lord Bravery finds he can't use his name (Someone else has the copyright), and the bureaucrat he's talking to keeps suggesting inane ones like 'Smoked Meats and Fishes' and 'Taste Of Tempura'.
Lord Bravery: ...You're a loon, aren't you? Right, where have you escaped from? I'll take you back!
At one point, he suggests Dreamworks and Bravery actually considers it, but its taken by someone else before he can choose.
In the episode "Hero Boy", Gutierrez makes a clone of Freakazoid to ruin his reputation. Luckily, Cosgrove soon realizes its a fake, and says as much to a group of reporters. When asked how he could tell...
Cosgrove: I invited him to go to the Yakov Smirnoff film festival. And he said no.
The running gag from Invisibo's episode where Dexter's family runs through random scenes screaming in terror, followed by Cosgrove asking if that was Freakazoid's family and Freakazoid responds with a dejected "Yeah."
An alien is abducting nerds. Cut to an episode of Regis and Kathy Lee, where Regis is talking (and talking and talking) and not letting his guest, the Pope, get a word in edgewise. Regis is then abducted by aliens, rapidly followed by Kathie-Lee. As Kathie-Lee disappears, we see the Pope smiling and clasping his hands in a praying gesture.
The creepy old lady who can only communicate by making creepy sound effects. At one point the narrator simply tells her to "Stop that and go away." When she gets attacked by one of Cobra Queen's giant snakes, the Narrator screams at her to run, and then is happy she got away.
Later, when the police are questioning her about what happened, she just makes more spooky noises before leaving in a huff after the policemen insult her.
