It’s Mike Birbiglia’s birthday today. Happy birthday, Birbigs!

It’s also the final weekend for his successful one-man show, Mike Birbiglia’s My Girlfriend’s Boyfriend, enjoying an off-Broadway run at the Barrow Street Theatre. Here’s ticket info for the final weekend of shows June 24-25, 2011. Birbigs won the Lucille Lortel Award this spring for outstanding one-person show, and deservedly so.

Even more emotionally engaging than his previous one-man show, Sleepwalk With Me, Birbiglia explores his path love, happiness and marriage — despite his long-seated misgivings about the latter and his struggles to find the former. You may have heard some chapters of this story as Birbiglia told them on radio’s This American Life or late-night TV spots. This, for instance, is Birbiglia’s story about his first girlfriend, as told on This American Life episode #374. And on Jimmy Kimmel Live last fall, Birbiglia talked about an even earlier experience with a girl and a ride on the Scrambler. There’s plenty of humor in these stories, but they’re also counterbalanced by a weight that hits close to every heart.

When he recently appeared on Late Show with David Letterman, Birbiglia performed a piece of his pre-show routine, in which he lets audience members to know to turn off their cell phones by joking about his own experiences with the phone company. It’s a nice touch, and allows Birbiglia to warm up the audience while giving them a chance to get used to his presence onstage as the storyteller.
