For eight seasons, Bill Cosby played lovable Cliff Huxtable on NBC's The Cosby Show. This week, the comedy legend is revisiting his role (and his signature ensembles!) with the "Cosby Sweater Tournament," a March Madness-style faceoff in which fans can vote for their favorite fibers on BillCosby.com. The competition kicked off with four "teams" – the Argyles, the Cashmeres, the Cardigans and the Pullovers (note: team names don't necessarily reflect sweater style) – and 32 memorable sweaters, and will whittle down to the "Sweat 16," "Fleecy 8," "Warmest 4" and "Champion Stitch" rounds.
