I would say, "Don't quit your day job, John Mayer," but I don't exactly want him writing and singing songs, so instead I'll say, "Please retire, John Mayer, and also tell Jessica Simpson that she looks weirdly monochromatic with her new ugly hair color that's the same color as her Mystic Tan skin, and is she really 26, because she looks about ten to twenty years older than that... You're still dating her, right? Oof, she must be pissed that her little sis is hotter than she is, and also that her boyfriend is better looking than you are. Ouch." That's what I would tell him.
