Good Homecoming Float ideas?

I am going to be a Sophomore in high school and every year for homecoming we build floats (Much like any other school). Every year our class always places last because our float ideas aren't the best. For example our float this last year when I was a Freshman was instead of "Silly Rabbit Trix are for kids." ours was "Silly honkers winning is for Mavericks." how lame is that. I was wondering if you had any ideas on what a cool idea for a float would be or a website that might have some cool ideas.
