Replying to Successful School Fundraisers

Alright, so the student council at my high school can't raise money for dick. They have all these awful, poorly planned fundraisers which never work, and I'm trying to help initiate some minute change in their pattern of failures. So far I have had two ideas: One, all the council kids don bikinis and trunks, stand against a wall, and we let kids pay a few bucks to throw water balloons at them. Two, some sort of drive in, old style movie night in the school parking lot. A ton of kids have cars, but I'm worried that this idea will be either a hit or miss, with no ground in between. Seeing as this list is currently looking pretty pathetic, I am coming on hand and knee to ask for your creativity, NS. Please don't disappoint.
