It's time for Jay Leno to hand over the Tonight Show reigns to Jimmy Fallon, and the long-time late night host gave his final bow on Thursday.

Attached to the NBC series since 1992, the 63-year-old briefly departed the program in 2009 but quickly returned after a short stint on The Jay Leno Show. Comedian Billy Crystal and country crooner Garth Brooks joined several surprise guests in saying goodbye to the long-time host.

The series walked down memory lane with Leno's monologue as the host listed off some of the differences between 1992 and 2014 (and a few unfortunate similarities) before a long list of celebrities gave him advice on what he should do next.

Crystal, who was Leno's first Tonight Show guest on May 25, 1992, then took the stage to perform a star-studded rendition of So Long, Farewell from The Sound Of Music. As Kim Kardashian, Jim Parsons, and Oprah Winfrey sang Leno's praises (literally), Jack Black reminded him that he may soon be back if Fallon drops the ball.

To conclude the night, Garth Brooks serenaded the crowd with The Dance before Leno choked up as he thanked his viewers, writers, and crew for an amazing 23 years.

The Tonight Show Starring Jimmy Fallon will premiere on Feb. 17 at 11:35 p.m. ET on NBC.
