It was the end of an era in late night TV last night. Jay Leno delivered a tear-filled goodbye on his last “Tonight Show” after 22-years. Billy Crystal was his final guest. Crystal was also Jay’s first guest when he took over for Johnny Carson in 1992. The longtime host said this was the best 22 years of his life and he acknowledged his staff for a great job. Jimmy Fallon will take over the gig when the show returns after the Olympics. Check out the tearful sendoff here!
