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."

" Leave it to me," said the principal. A week later he phoned the boy's father. "I think I've cured him," he said.

" How?"

" 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 "

" What happened?" asked the father.

" 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."

" No, it won't," said the father. "He bet me $10 this morning that he'd pull your beard with your permission by the 

end of the week!"
