Games to play at a birthday party?

I am having a sweet sixteen in about a month and a half, and I am trying to think of games to play. It's going to be a kid theme, just because when people turn 16 they are usually all about being adult and mature--I dont think so! haha so I just need some fun, creative games to play. I'm already planning on having a blow up slide or bounce house, and I'm thinking about a scavenger hunt around the neighborhood. I'll have 7 guys and 7 girls, but no games like spin the bottle or anything like that.
