The American Music Awards teased Psy's performance all night long, promising a special guest would appear with the K-pop star on "Gangnam Style." Given the number of people Psy has gotten to know this year, there was a long list of possible collaborators. Would it be Madonna? Britney Spears? United Nations Secretary-Genearal Ban Ki-moon? Nope: It was MC Hammer. (Maybe Psy's Hammer pants should have been a tip-off.)
Midway through Psy's performance, the lights went dark for a moment, and then Hammer was there, "Gangnam Style" morphed into "2 Legit 2 Quit" and back again as the pair rolled through moves like each was born to do the other's dance.
