Who doesn’t enjoy a good nail through the nose? Stephon Walker certainly does. But when we met the artist better known as Swami Yomahmi in the middle of Silver Sprung, we barely recognized him. No nail, and no turban.

But we weren’t disappointed, because Walker’s inner geek is never far from the surface, and when the Green Lantern oath came up in conversation, we got to strut our own geekiness a bit.

A founding member of the Cheeky Monkey Sideshow, which played at last year’s fest, the Swami is bringing his “Unnatural Acts of Comedy” show to the Scientarium this year, which sounds like a good match of venue with performer.

Do pay attention, because in this video the Swami does indeed perform an unnatural comedy act. I’m surprised he survived…

Swami Yomahmi: Unnatural Acts of Comedy is at the Scientarium, 709 D St. NW, on Tuesday, July 24, at 7 p.m.; Wednesday, July 25 at 9:30 p.m.; Friday, July 27 at midnight; Saturday, July 28, at 2:30 p.m.; and Sunday, July 29, at 2 p.m.
