Spiritual father to every Philadelphian ever Bill Cosby went on Late Nite With Jimmy Fallon on Friday, and guess what? He slayed. He clowned The Roots (called Black Thought “Ty-reek Trot-Trotter,” dropped a quarter in Tuba Gooding Jr.’s tuba, etc.), kept Fallon on his toes with long bits of actually pretty edgy weirdo comedy riffs and then held court with Tempestt Bledsoe. If you’re a fan, you really owe it to yourself to check out the full episode, and if you’re a superfan, we’ll tell you this: The Cos plays the Keswick on April 7th, and if you’re a Hulu Plus subscriber, you can watch every episode of The Cosby Show ever made (we are, and it’s a huge quality of life jump, who knew?).
