(slightly off-topic)

When I was young, all my jokes were from somewhere else (101 funny jokes!) and people thought they were funny. My problem was remembering them.

Nowadays everybody has seen all the good ones ("Bring me my brown pants!")

So now the problem with telling jokes from a "professional funny person" is that if you've heard it before, chances are others have too and you're getting polite laughter.
