John Mayer - Douchebag or Not?

Honestly, I like John Mayer as a musician, but why does he say stuff like this?

"What if I had a booth on the street and I said, 'Attention, everybody who hates me: If you have a problem with me, I'm ready to hear your gripes! I will be outside the Barneys store on 60th Street from two to four this afternoon. I will not be speaking to fans. I will only be speaking to people who do not like me. Come out and let me have it. I will not speak back.'
"How many people do you think would be standing there? I'm talking about people getting the chance to tell me directly, 'I think you're a douchebag.' You know how many people would do it? Ze-ro. You know what they'd do? They'd walk up and say, 'I'm just messin' with ya.' And you know what I'd say? I'd say, 'You're a douchebag!'"

You set up that booth you sh*thead. See what happens.
