Sisqo's ''Thong Song''

It takes a certain je ne sais quoi to get Academy Award winner Susan Sarandon waxing poetic on butt floss, but this platinum-haired crooner pulled that off and a lot more during his appearance on VH1's Men Strike Back — the male version of Divas — last April. After Sarandon introduced his ''Thong Song'' as the spring-break anthem for skimpy skivvies... and the tushy-worshiping souls who love them, Sisqo delivered a showstopping number featuring one-armed cartwheels and an update of the moonwalk. When he crooned the song's final note among a gyrating mass of bikinied, lingerie-flashing dancers, he made sure no one will ever look through a Victoria's Secret catalog again without humming his tune.
