What is the most memorable (in a good of bad way) thing you've ever been dared to do and done?

For me it would have to be when one of my cousins vrienden dared me to strip at my cousins party. I did to and had a good time. Although to say no one has forgot it wouldn't be true but saying everyones heard about it would be.

I have gotten myself in odd situations like that many times but sad to say that was the most memorable even if I will never live it down.
