John Mayer's recent ode to Borat proved that he's willing to put his balls on the line for a good gag. And he was back in action today, messing around with the paparazzi in Hollywood.

But does Mr. Wonderland deserve "double-threat" status?

Mayer has scored laughs on "Chappelle's Show" and "Saturday Night Live," and his Internet vids have clogged YouTube for years. Yet the few times he's mounted the stand-up stage, his reviews have been mediocre at best. And is it really that hard to put on a green thong and jog around a cruise ship?

Is John Mayer genuinely funny? Or is he just young, rich, bored and in possession of a video camera?

Review the video evidence -- and you decide.
