Jay Leno  stepped down from his late-night throne (for real this time), and Kim Kardashian , Oprah Winfrey , and a few more familiar faces showed up to say goodbye. That's right, the final episode of The Tonight Show With Jay Leno aired Thursday night, and it looks like it was a big event! Jay really came full circle with his final guest, Billy Crystal, as Billy was his first guest when he took the reins from Johnny Carson back in 1992. The remainder of the night's events featured a reported rendition of "So Long, Farewell"  from The Sound of Music, where everyone from Oprah to Kim was a participant. Check out the photos below, and get ready, because Jimmy Fallon  takes over The Tonight Show on Feb. 17!
