What would be a better choice for a fundraiser for cancer research?

So this is a repeat question, but I want to try and get more of a response. I wanted to do something fun, silly, and out of the ordinary. I was talking via e-mail with an owner of an adult footed pj company, and she thought it would be awesome if I was to collect money and wore footed pajamas for one weekend. I then thought maybe not so much footed pajamas, but maybe pajama bottoms and some silly slippers. My other idea was to host an adult pajama party and pay a cover charge. What do people think? No matter what is chosen, I would love some ideas on what style of pajama or fun activities for the party?
