IF YOU HAVEN’T SEEN Jerry Seinfeld’s movie, “Comedian,” you should. If it’s not playing near you, or if it’s no longer playing anywhere, buy the video when it hits the stores. Watch it often, buy several more, and give them to your friends, especially anyone who’s ever said, “Ooh, I love ‘Survivor.’ Wouldn’t miss it.” Then insist that they pick up a bunch themselves and give them to their friends.
