Presented most Wednesdays by the People’s Republic of Komedy, this long-running comedy variety show was once crashed by Robin Williams and has been frequented by comedians from Eugene Mirman to Cathy Sorbo. Laff Hole features sketch comedy, stand-up and live music from bands like Troy Nelson’s comedy band Black Daisy and up and coming electro act Natalie Portman’s Shaved Head.
