'Welcome Back, Kotter' is one of those shows you stay home on the weekends for. I know I do. From the puberty-neglected voice of Arnold Horseshack to the feathered and Jew-froed hair of Vinnie Barbarino, Juan Epstein, and Gabe Kotter, everything about this show is classic. At first glance it might just seem like some kitschy little retro sitcom, but make no mistake, it is awesome. By the last season the show slowed down and became a shadow of it's former self, but if you can ignore that then you will see that this show is one of the best ever.
