* AdamWesting: Creator/StanLee voices a deranged version of himself.
-->"He can't be the Hulk! I'm the Hulk!"
* ActuallyThatsMyAssistant: A pretty pathetic example when Kirk speaks at career day.

When do I get paid?"), but won't be paid until 2012 ("D'oh!")
* BodyHorror: When trying to suppress his anger, boils keep popping out of Homer's neck until a whole bunch of them spring up.

'''Comic Book Guy:''' Oh, please! You couldn't even turn into Bill Bixby!\\
'''Stan Lee:''' Mmmmm! Aw, forget it. Mm-mmmm! I really did it once!\\
'''Comic Book Guy:''' ''[walking Stan Lee in the store]'' Yes, yes. I just wish you had the power to leave my store.\\

* RageBreakingPoint: Homer finally lets his surpressed anger loose when he falls into a kiddie pool filled with green paint.
* RealityEnsues: Homer doesn't really [[HulkingOut Hulk Out]], he just gets ''really'' angry. And despite that, he's still easily subdued by the police.
