Hilarious jokes

The teacher said to his class one day, "Please stand up, anyone who thinks they're stupid."

Nobody stood up so the teacher said, "I'm sure there are some stupid students in this class!"

At this point Little Johnny stood up.

The teacher said, "Oh Johnny! So you think you're stupid then?"

Little Johnny replied, "No, I just felt bad that you were standing up on your own."

A dog walked in to the telegram office one day. He took out a blank form and wrote on it:
"Woof. Woof. Woof. Woof. Woof. Woof. Woof. Woof. Woof."

Then he handed it to the clerk. The clerk examined the paper and said to the dog, "You know there are only nine words here? You could send another 'Woof' for the same price."

The dog replied, "But that would make no sense at all!"
