Ever since John Mayer hooked up and broke up with Jessica Simpson he has adopted some ridiculous sexy/funny guy routine. I appreciate self deprecating humor as much as George Clooney does, and get the "I'm a huge star" humility thing, but he's not quite cool enough to pull it off... although he's trying like hell.
When he's not cracking us up with his wit and sarcasm, he's collecting tattoos and new muscles on his wonderland. Tats + muscles= instant coolness.
He's got some cruise called the "The John Mayer Cruise", the "Mayercraft Carrier", where he shocked and entertained his crew this weekend by donning the joke that's already been done Borat thong.
Ha ha larious.
