Are men much better than women at making stupid "bets"?

My husband has lost several bets in the past with co-workers. Twice he had to wear a dress to work. I’ve got the pictures, want to see?

He came home tonight and told me of yet another bet he made with a co-worker.

This made me think… When I was in the work force I don’t recall one moment when a female co-worker tried to make a bet. Is this mainly a “guy” thing?

Females: Do you make bets with friends or co-workers?

Anyone: What’s the most embarrassing thing you have had to do because you lost a bet?
