Add former Seinfeld star Jason Alexander's name to the list of entertainment heavies with guest-spots on NBC's Friends among their credits. Set for a February sweeps appearance, the funnyman will play a suicidal guy whom Phoebe (Lisa Kudrow) calls while working at a telemarketing firm. The show promises quite a line-up for the month. Oscar-winner Susan Sarandon is also set to show up in a separate episode, playing a Days of Our Lives actress who's canned from the show and must be told by the hapless Joey (Matt LeBlanc).
