And this is one of the best reasons!
In this hilarious clip from the film, Franco's character Dave Skylark is interviewing rapper Eminem.
During the interview, Eminem casually comes out
We have the perfect pick up line for John Mayer to use at a club: "Hi, I'm John Mayer."
Okay, so maybe John wasn't exactly going to any sort of twerk-heavy nightclub with a name that only Stefon could come up with. He went to a jazz club!
He was there to see pianist Chick Corea's show, before Chick played with him and the rest of the John Mayer Trio on Thursday's Late Night with Seth Meyers.
We wonder if other audience members went up to John during the performance, and asked him, "are you doing a solo?" Then he went on Facebook and looked at a picture of him and Katy, and said, "I guess I am doing this solo."
