Joke of the Week

We were having pizza tonight with some of the young people I work with. One of the young people told this joke:

A man walks into a pizza shop & orders a pizza. The man behind the counter asks him "would you like it cut into 4 pieces or 6 ?"

The customer replies "Oh only 4 pieces, I couldn't eat 6."

We actually thought it was quite funny - until he proceeded to explain the joke......
