HBO Comedy features an early-morning treat at 5:25 a.m. Tuesday with the rebroadcast of Rodney Dangerfield's 1987 young comedians' special, "Nothin' Goes Right." What makes this special special? How about an early look at what would become Andrew "Dice" Clay, on the same lineup with Bill Hicks, Carol Leifer, Dom Irrera, Robert Schimmel and Lenny Clarke. Haven't seen this show in a year or so, but I can tell you already that Clarke's bit about terrorist hijackers might not wear its age so well. Let's give the whole episode a new look-see and reconvene here tomorrow.
