Marc Maron’s “WTF” podcast will welcome its least seasoned comedian yet on Friday: Maron today announced that President Barack Obama would be his next guest, in an episode that will debut online Monday. As always, the interview will take place in Maron’s garage, a fact that has resulted in some unusual attention from the Secret Service. “Oh my God, I hope my bathroom’s clean,” Maron joked on Friday’s episode. “We let the neighbors know. My producer has been at the house dealing with Secret Service. My street is going to be incredibly safe for the next few days.” President Obama is expected to discuss his political career, the challenges of office, and the time he opened for Sam Kinison at the Comedy Store in 1989.
