Which came first for Dr. Bob Baker, putting his hands inside people’s rectums or inside puppets to make them talk?

That’s not a rhetorical question.

Baker, who bills himself as “America’s funniest gastroenterologist,” decided at the age of 9 that he also wanted to be a ventriloquist. So he does both. Baker also counts Howard Stern as a patient. The small world circled unto itself on last night’s episode of America’s Got Talent on NBC, wherein Baker auditioned, Stern acknowledged that Baker is his doc and performed Stern’s colonoscopy, and even you can prevent forest fires but cannot prevent yourself from writing your own jokes about this hyper-meta reality play you see before you. Bonus points to whomever on the show’s production team decided to cue up Howie Mandel’s¬†St. Elsewhere¬†soundtrack!

Roll the clip.

Dr. Bob Baker’s comedy site notes that he has several ventriloquism puppets — not only Sigmoid Colon, but also three “people” puppets, Mrs. Lucille Goldman, Oscar Makyne and Archie P. Nelson.

Last year, Baker performed at the annual Vent Haven ConVENTion for ventriloquists in Kentucky. How’d his jokes go over with that crowd? A lot better, as you might have expected.

Roll that clip!
