When comedians open for rock bands — something that seems to be happening more and more lately — it can be a bit awkward. But when Hannibal Buress (actual name) did a quick stand-up stint before Handsome Furs played at Music Hall of Williamsburg a few weeks ago, his observational humor was right on point: "I live in Williamsburg, and there are a lot of cats with handlebar mustaches walking around. I'm cool with it, but don't talk to me like you don't have a handlebar mustache. You should be talking to me about kazoos." The man has a point.
