     BURBANK, Calif.  
   (AP) -- Jay Leno has said goodbye to "The Tonight Show" before, but 
not like this. The comedian became tearful and choked up Thursday as he 
concluded what he called the "greatest 22 years of my life."
"I
 am the luckiest guy in the world. This is tricky," said the emotional 
Leno, stepping down for the second and presumably last time as host of 
TV's venerable late-night program. Jimmy Fallon takes over "Tonight" in 
New York on Feb. 17.
Leno shared that he'd lost his mother the first year he became "Tonight" host, his dad the second and then his brother.
"And
 after that I was pretty much out of family. And the folks here became 
my family," he said of the crew and staff of "Tonight."
It
 was a tender finish to a farewell show that was mostly aiming for 
laughs, with traditional monologue jokes, clips from old shows and a 
wild assortment of celebrities helping to see Leno off.
Leno
 first departure came in 2009, when he was briefly replaced by Conan 
O'Brien but reclaimed the show after a messy transition and O'Brien's 
lackluster ratings. In `09, he was moving to a prime-time show on NBC; 
this time he's out the door, and has said he'll focus on comedy clubs 
and his beloved car collection.
Looking sharp 
in a black suit and bright blue tie, Leno was greeted by an ovation from
 the VIP audience. The typically self-contained comic betrayed a bit of 
nervousness, stumbling over a few lines in his monologue.
He didn't trip over his opening line, though - a final dig at his employer.
"You're very kind," he told the audience. "I don't like goodbyes. NBC does."
Leno
 brought his show full circle with Billy Crystal, who was his first 
guest in May 1992 and his last guest Thursday. Crystal played ringmaster
 at one point, calling on Oprah Winfrey, Jack Black, Kim Kardashian, 
Carol Burnett and others for a musical tribute to Jay with a "Sound of 
Music" song parody.
"So long, farewell, auf wiedersehen, goodbye. If Fallon tanks you'll be back here next year," sang Jack Black.
"The
 Big Bang Theory" star Jim Parson's contribution: "We've watched you 
when we're weary. Your great success is called the big chin theory."
In a videotaped segment, celebrities offered career advice to Leno.
"Why would I give a (expletive) about what he does. He's a grown man," said Mark Walberg.
President Barack Obama, like other politicians a favorite target of Leno's, struck back in his clip.
"Jay,
 you've made a whole lot of jokes about me over the years, but don't 
worry, I'm not upset," Obama said, adding that he was making Leno the 
U.S. ambassador to Antarctica. "Hope you have a warm coat, funnyman."
Crystal
 sang Leno's praises during the show, saying the late-night host made 
America feel a little better at bedtime and invoking his predecessor, 
Johnny Carson. Leno's "Tonight" tenure was second in length only to 
Carson's 30 years.
"You were handed the baton 
by one of the all-time greats. But once it was in your grasp, you ran 
the race," Crystal said. He and Leno, longtime friends, reminisced about
 the old days, with Leno recalling how Crystal and other comedians 
visiting his town, Boston, stayed in Leno's apartment.
"You're calling it an apartment. I'm calling it a bomb site," Crystal joked.
Leno
 told how he was poised to make his network debut on Dean Martin's show 
in 1974 when news came that President Richard Nixon had resigned in the 
Watergate scandal. Leno's appearance didn't happen.
"Making me the last guy screwed by Nixon," Leno said.
Garth
 Brooks performed his touching song "The Dance" before Leno's farewell 
remarks. "Now that I brought the room down," Leno joked, he asked Brooks
 to lighten it up.
Another Brooks' song, "Friends in Low Places," closed out the show.
"It's
 going to be difficult to not come in and do a show every day for our 
audience who has been so great to Jay," lamented Vickers, the executive 
producer. "And also hard for this group of people (the staff) who have 
all been together for 22 years," said Vickers, who worked on Johnny 
Carson's "Tonight" before taking the top job with Leno.
Leno,
 63, said he plans to continue playing comedy clubs, indulging his 
passion for cars and doing such TV work as comes his way - other than 
hosting on late-night.
"It's been a wonderful job. This is the right time to leave," he said last week, and make way for the next generation.
Fallon,
 39, starts his "Tonight" Feb. 17, with NBC hoping he rides the 
promotional wave of its Winter Olympics coverage the next two weeks.
Closing
 his final show on Thursday, Leno gave a final shoutout. It was to his 
wife of more than 30 years, Mavis: "I'm coming home, honey!"
