Comic Book Guy: I would like to return your quote-unquote 'ultimate' belt.
Sarcastic man: I see. Do you have a receipt, quote-unquote 'sir'?
Comic Book Guy: No, I do not. I won it as a door prize at a Star Trek convention, although I find their choice of prize highly illogical as the average trekkie has no use for a medium sized belt.
Sarcastic man: Ooh, a fat sarcastic Star Trek fan, you must be a devil with the ladies!
Comic Book Guy: {Struggles to find the proper comeback}
Sarcastic man: I hate to break it to ya Casanova, but no receipt, no return.
