Maybe we should have known this was going to happen when Psy began his performance in black parachute pants. Maybe we should have known because Psy is the spiritual successor to MC Hammer. Maybe we should have known because it just kind of had to happen: When someone figured out that they're backing beats were the same, a mashup of "Gangnam Style" and "2 Legit 2 Quit" would become the peak of dance music history. And so last night, it happened. Psy and MC Hammer performed together to close out the American Music Awards. It pretty much ruled, and it erased any of the bad vibes that came from Justin Bieber winning Artist of the Year a few minutes prior and giving a speech talking about his "haters."

(Also: When Hammer got the phone call about this job, how long did he wait before accepting it? 2, 3 seconds? Less?)
