Any ideas on a great all-American theme for a parade in college?

hey. do you guys have any suggestions on a theme for a parade coming up pretty soon in my college? i am currently not in the US, but we're planning something American, because we are flying to US soon to further our studies. we did something like American movies before, so if you guys can think of something similar? about 20+ classes are participating. thanks =DAny ideas on a great all-American theme for a parade in college?What about American sports ? After the parade you would still get use out of the clothing and equipment .
