Have you heard the one about the new trend in standup comedy? Cleanliness. Good money is being made by unsmutty comics like those represented by Cleancomedians.com. These people perform at corporate events, guaranteeing inoffensive material under the slogan "It Doesn't Have to Be Filthy to Be Funny."

What a load of %!$#. To me, humor requires edge, and raunchiness in the service of edge is no crime. So, aware that Cleancomedians.com is hungry for publicity, I challenged some of its best standup comics to a fight. I would write the setups to jokes, and they'd try to complete them, squeaky clean.

Yes, I fought dirty.

A Jewish guy and an Iranian Muslim woman fall in love and decide to marry. The guy goes to his rabbi and says: "I have a problem. Through her veil I can see that Fatima has a lovely face.

The rabbi smiles, hands the guy a banana and says,

"In that case, you might find this more a-peeling." (Adam Christing)

"Because you love her soul, you will think her beautiful, regardless."

"Good," the guy says. "But what's the banana for?"

"Because it'll make four minutes seem like forever."
