Psychology?...
A very shy young student goes into a pub and sees a beautiful young lady sitting at
the bar. After an hour of gathering up his courage he finally goes
over to her and asks, tentatively, "Um, would you mind if I chatted
with you for a while?"
She responds by yelling, at the top of her lungs, "No, I won't sleep
with you tonight!" Everyone in the pub is now staring at them.
Naturally, the young student is hopelessly and completely embarrassed and
he slinks back to his table.
After a few minutes, the young lady walks over to him and apologises. She
smiles at him and says, "I'm sorry if I embarrassed you. You see, I'm
a graduate student in psychology and I'm studying how people respond
to embarrassing situations.
"
To which he responds, at the top of his lungs, "What do you mean,
£200?"
