No comedian this week is likely to give you that "Where the hell have I seen that guy before?" vibe more than Michael Bunin. For starters, he's a Las Vegas product, having attended UNLV. But he's also appeared in more than 50 national commercials (What, you need a few hints? Tostitos, Hormel and Office Depot) and several popular television shows. (More hints? Gosh, you people are pushy! Scrubs, CSI and Without a Trace, okay? Now leave me alone!) But he's best known as Kenny Moritorri on TBS' clever ensemble comedy My Boys.This weekend, he headlines the Playboy Comedy Club along with Boys co-star Jamie Kaler as part of their Men of My Boys Tour. Bunin has some serious improv chops, having perfected his craft at Second City in Chicago and the Groundlings in Los Angeles. If you've seen the byplay between Bunin and Kaler on TBS, you have only a small inkling of what you're in for.
