Betty White's 90th birthday: A proposal and much more

To celebrate Betty White's 90th birthday, which is January 17, famous TV stars and comedians gathered together for a star-studded bash that aired Monday night (Jan. 16) on NBC. Check out this clip for some highlights.

"Betty, you're going to hear a lot of jokes tonight about your age. But take comfort in the fact that come tomorrow, you won't remember any of them," says Amy Poehler.

"Like many of you, I first heard about Betty from the wonderful stories told to me by my grandmother," says the 78-year-old Carol Burnett.

"Chuck" star Zachary Levi actually proposes: "I would like to be the mother of your children ... I think that this could really work out in a myriad of ways. I'd take your last name ... Zach White sounds good, plus Betty Levi is like Carol Channing's weird sister in 'Hello Dolly.'"

Betty then lays one on Zachary. You go, Betty. And happy 90th birthday!
