I’m not entirely sure if this opening line is brilliant or brilliantly awkward, but I am convinced that Dylan Moran gave 100 percent of himself to this performance last night on Late Show with David Letterman.

Moran’s an Irishman. His first stand-up tour of North American theaters begins this weekend with Just For Laughs Chicago. Check out his other tour dates here.

Now check out Moran pointing out all of the things you put in your mouth, by listening to him talk out of his mouth and into your ears.

Roll the clip!
