I need a really really cute way to ask a boy to the sadies dance!?

I was going to do it with goldfish crackers, and swedish fish candies and spread them all over his room, and get 2 real goldfish, and hanging cardboard fish from ceiling, and throw go fish cards all around his room with my name on one, and make a poster that says, "out of all the fish in the sea will you go to Sadie's with me?" but i was telling my friend this and she said everyone does this.... i want something unique and creative... something that i still get to decorate his room though! i'd really appreciate it :)
