John Stamos, Nick Jonas, and Joe Jonas win the award for weirdest/best collaboration ever!

Yeah, we're not really sure what else to say other than WTF and HOLY AMAZING because Joe Jonas and Nick Jonas just duetted with John Stamos, aka Uncle Jesse from "Full House"! We know -- it's hard to believe that in between having a bazillion brunch dates, announcing reunion shows (!!), writing music, in-studio Nerf Gun wars, and Twitter hacking, that Joe and Nick found the time to visit Uncle Jesse's ::cough:: I mean, John Stamos' gig at famed NYC venue The Bitter End. But it happened, it was real, and it RULED.

Watch Joe and Kevin Jonas sing "Superstition" and "Can't Take My Eyes Off Of You" with John Stamos after the jump.

During their cameo, the boys performed two songs, "Superstition" and "Can't Take My Eyes Off Of You," while John Stamos handled things on the drums. And no, just like you, we have absolutely no clue how John Stamos knows the Jonas Brothers (maybe they ran into each other at a hot dude convention?), but per Nick Jonas' Twitter, they're great pals: "So fun playing music last night with @JohnStamos @JoeJonas and the awesome band over at the bitter end." Well there you have it, ladies and gents! The most unexpected, yet totally awesome collaboration of the 2012 season.
