Koz cries out “I’m not worthy!” as he interviews one of the greatest SNL stars of all time, and learns about how Mickey Rooney was “out of his mind and carried a .38 pistol on him at all times,” how he came up with the “Chopping Broccoli” song and how it’s followed him for the past 28 years, how the Church Lady was rooted in his passive-aggressiveness, how Garth started, who were his favorite and most difficult impersonations, why it’s complete bull that only left-wingers can make political comedy funny, his friendship with the first President Bush, and his memories of Louis CK, Steve Carell and Stephen Colbert from “The Dana Carvey Show.” Oh yeah, and he also does his impression of Scarface at Thanksgiving and a little someone called The Church Lady, plus Johnny Carson and his offshoot Carsenio. All in a half hour. What’s not to love?
