In middle school, John Mayer played clarinet with little success. After watching the movie Back to the Future, Mayer was inspired by Michael J. Fox's guitar scene to pick up the instrument himself. "My father rented an acoustic guitar from the music store," Mayer recalled to ABC News. "I remember looking at the guitar going, 'Well, if I knew how to play you, I would play you.' And it was that simple. It was just like, I'm not gonna stand for not knowing how to play this. And I still don't."
Although he's had several songs at the top of the charts, John Mayer considers "Your Body Is A Wonderland
" to be his only "hit" song. In an interview with Rolling Stone

The second went to Mexico aboard the Carnival Splendor in 2009.
