Young fellow goes to University to study logic.
Christmas Eve, following his first semester, he is in the local pub and is asked by one of the locals to explain "logic".

He decides to use an example.

"Do you have a gold fish at home?".

"I do" replied the local..

"That suggests you have children".

"I do" replied the local.

"That suggests you are married"

"Remarkable", says the local.

"That tells me you are not a homosexual"

"Unbelievable", says the local.

****************************

In comes another local to the pub.

"I saw you talking to the young fellow, what is he doing in University?", he says.

"Oh, he is studying logic"

"Whats that?", says local Number 2

"Well, I'll give you an example, have you a gold fish at home?"

"No"

"Well, you're a homosexual"

************************

I quit, before I offend anybody else.
