Here's one very stupid joke early in the morning for you people.
"If there are any idiots in this room, will they please stand up" said the sarcastic teacher. After a long silence, one freshmen rose to his feet. "Now then mister, why do you consider yourself an idiot?" enquired the teacher with a sneer. "Well, actually i don't," said the student, "but i hate to see you standing up there by yourself."
