R&P: Which one of these young men is the biggest d-bag?

That is really hard because they are all d-bag's, except John Lennon, John Lennon was in no way a d-bag. I really really don't like John Mayer only because he will f*ck anything that walks, and he makes terrible music!!!! Pete Wents is a dick though, and so is Travis Barker. I declare it is a tie between Travis Barker, Pete wents, and John Mayer.
