I'm a terrible dancer, but I guess being with other FIRST people who are just like me makes me care less about embarassment, so much that the guy in charge of video on my team included me making a fool of myself dancing in a recent promo video for the team. Ah! I can't help it. I'm reserved all other times...
Guess that answers why there are so many good dancers in FIRST. Some people end up being far less embarassed, therefore go nuts.
