I've written plenty about musician John Mayer's sincere efforts to perform stand-up comedy on the side, and spoken at length with John Mayer one night about how his attempts at comedy sometimes can go far, far astray. He cares about comedy as an art, even if he doesn't always get it right, or yet to figure out how to balance his real-life rock star persona with the material he's saying onstage. That said…

The Upright Citizens Brigade took aim at Mayer in their latest original UCB Comedy video, in which narrator Matt Besser, John Gemberling and Brett Gelman, among others, discuss the notion of "Funny John Mayer" as just an urban legend. The YouTube comments, not surprisingly, are a bit of a hoot, with Mayer's fans calling out the UCB. Roll the clip!
