Little Johnny was in the kitchen playing with his toy train while his dad was cooking dinner. Johnny stops the train at the station and says, "All of you bastards who want to get off, you're here, so get the fuck off. And you dirt bags waiting to board, get your asses on now or we leave without you!"
"Little Johnny!" shouted his father. "I can't believe you are using that kind of language! You should be ashamed of yourself! Go to your room and don't come back until you have thought about what you've done!"
So Little Johnny goes to his room and about an hour later he returns. Once again he starts playing with his toy train, only this time when he comes to the stop at the station he says, "All of you fine ladies and gentlemen who want to get off, you've arrived at your destination, you may now exit the train. And all of you nice people who are are waiting to get on, welcome aboard! As for anyone who has a problem with the one hour delay, take it up with the asshole in the kitchen!"
A woman yells out, "No, I won't sleep with you tonight, you pig!" Everyone in the bar stops and stares. Completely embarrassed, the guy slinks back to his table with a red face.
After a few minutes, the woman walks over to him and apologizes. She smiles and says, "I'm sorry if I embarrassed you. I'm a graduate student in psychology, and I'm studying how people respond to embarrassing public situations."
To which the guy responds as loudly as possible, "What do you mean $200 for a blowjob?"
