Good Button Designs?

[Zholl]

One of my personal favorites was one of NERD's buttons two years ago, which I got at Championships. It said "I'm with NERD" (or something like that. I'm too lazy to go find it right now) with a big arrow pointing to the side, ala those "I'm with stupid" shirts. The design and phrase were short and simple, but still creative and fun, and it just sticks out in my head as far as buttons go. Another one that sticks out is from the Pink Team, and simply says "TEAM PINK" in big black letters on a hot pink background. Not necessarily the most creative or original button, but still bold and memorable, and one of the few I've found excuses to wear outside of my robotics regalia
