(paraphrasing, heard this on 'RawDog' sat radio comedy channel.)
A guy picks up a prostitute and asks how much for a BJ. She says $100. He's desperate and hasn't been able to find anyone else so takes her back to his room and immediately starts jerking off. She asks him wtf he is doing and he says "For $100 I'm sure as hell not gonna give you the easy one".
