The FAMU Band. Where does one begin? Start with the drum majors--even when you're in the nosebleeds, you know something's going on, since even from the distance of several miles you can look at the drum majors and guess that a.) they're not gay, b.) they're dancing better than you, even in your drunkest fantasies, ever have, and c.) they're getting straight laid that night.
To properly appreciate FAMU, you have to see the choreography up close, and since most of the videos of the band on YouTube are straight pressbox shots sprinkled with occasional close-up shots, you miss out on plenty of quality pelvic thrusting and leg grabs. The practice videos show their whole routine, though, complete with crowd participation and singalongs. The best comes about a minute in, and yes, you get bonus points for getting people to attempt this in the office.
