After 22 years hosting The Tonight Show on NBC, Jay Leno went out the way he started: with Billy Crystal at his side! Billy was Jay's first guest back in May of 1992 so it was only fitting that Jay invited the comedian back for last night's final show. Not content with just a simple sendoff, Billy paid tribute to Jay with a musical tribute that the Von Trapp family would have been proud of. It was a star-studded affair with the likes of Oprah, Jack Black, Kim Kardashian, Sheryl Crow and Carol Burnett!

If you feel like taking a walk down memory lane, here is the video of Billy's first visit to The Tonight Show back in 1992:
