The cast of 90's teen sitcom Saved By The Bell were brought back together for a one-off skit on The Tonight Show with Jimmy Fallon.  From Zach to Mr Belding and Kelly Kapowski it was a nostalg-a-thon, with the cast looking scarily like they've not aged at all!  Unfortunately Dustin Diamond, aka Screech, had 'prior commitments' with his attorney.
