"Leave it to me," said the principal.

"I want you to help me stop my son gambling." an anxious father said to his boy's principal. "I don't know where he gets it from, but it's bet, bet, bet."

"Well, I saw him looking at my beard and he said, 'I bet that's a false beard, ' How much?' I said, and he said '$5'"

"No, it won't," said the father. "He bet me $10 on Monday that he'd pull your beard with your permission by the end of the week!"

A week later he phoned the boy's father. "I think I've cured him," he said.

"How?"

"Well he tugged my beard which is quite natural and I made him give me $5. I'm sure that'll teach him a lesson!"

"What happened?" asked the father.
