I think it would be a true accomplishment for a woman to go out and eat alone.

It would significantly alter he world view in a powerful and Earth shattering way. And all she would have to do is, well... eat alone.

This would make a good bet. Offer some chick $50 that she can't do it. If she refuses she looks completely insane and you can ridicule her to no end.
