Heres my fave two comic book guy lines
Bart - Can I buy a copy of Bonestorm for 9.99 (Handing over his money)
Comic Book Guy Opens the till
CBG - Yes of course you can net proffit to me -39.99 please take the money out of the till
Bart goes to take the cash
CBG - Scince we are cleary unfamiliar with the concept of sarcasm I will be closing the till at this point.
or
CBG - Excuse me I would like to return this quote unquote ultimate belt
Store Guy - do you have receipt quote unquote sir
CBG - no for I won it at a star trek convention however I find their choice of prize higly illogical as the average star trek fan has no use for a medium size belt.
Store Guy - Oh fat sarcastic star trek fan you must be a killer with the ladies
Bart - Ill give you five bucks for it
CBG - Fine i must return to my emporium where it is I who dishes out the insults instead of absorbing them
"A noble spirit embiggens the smallest man"
"Embiggens, phfft that isn't even a word"
"Of course it is Lisa, it's a perfectly crumulent word"
