Tonight Show host Jay Leno signed off on his 22-year career behind the desk Thursday with a few jokes and plenty of tears. In his final monologue before turning the reins over to Jimmy Fallon, Leno cracked, "When I started hosting, Justin Bieber wasn’t even born yet. That's why we call those the good old days." The rest of the show featured a star-studded lineup that included Billy Crystal, Oprah, Carol Burnett, Garth Brooks, and for some inexplicable reason, Kim Kardashian. In a taped message, President Obama offered Leno a job as an ambassador to Antarctica. By the end of the night, Leno choked up as he addressed fans and thanked them for being a part of "the greatest 22 years of my life." But his last shout-out went to his wife of more than 30 years, Mavis: "I'm coming home, honey!"
