Michael Somerville made his debut Thursday night on Late Show with David Letterman.

Somerville explains how his definition of “in shape” has changed as he has grown up. Is he in shape? Does having soft hands count? He is still single, which is different from his best friend. At least his buddy knows someone who can handle his laundry and furnishing needs.

Roll the clip.

If you enjoyed that, then you can check out his new CD, “Handsomely Disheveled,” on iTunes.
