The cast of 'Seinfeld' sure are having a nice couple of days, what with a 60 Minutes poll declaring the series the greatest sitcom of all time, and Michael Richards' TV return, but the best news of all might belong to 'Community.' We've just learned that a former 'Seinfeld' star will go from TV's greatest sitcom to its most under-appreciated, guesting in 'Community's upcoming fourth season. So what's the deal with Jason Alexander's top-secret 'Community' season 4 gig?

Could George be the new Pierce? The rumors are bound to fly now that we've learned from The Hollywood Reporter that acclaimed 'Seinfeld' star Jason Alexander will make a guest appearance in 'Community's fourth season. Details of the role are being kept under wraps for the moment, but those following recent 'Community' news will remember that series star Chevy Chase's exit from the cast left two episodes of the upcoming season to be filmed without his character Pierce Hawthorne. Might Alexander be a joking recast, or a new character altogether?
