Joan isn’t willing to celebrate her birthday, but at least she’s got an appearance on Late Night with Jimmy Fallon.

From Sabrina’s bachelorette party to Joan’s interest in finding Melissa a new man, this is what happens in Vegas with the Rivers clan.

You know what they say about New York: There’s never a dull moment, especially when the Rivers are in town!

For Joan, it is so wonderful seeing Sabrina’s wedding because it means someone’s marriage in her family actually worked.

In this deleted scene, Melissa and Cooper take Grandma out for a fun birthday lunch that involves cooking your own food, but Joan finds a better use for the stove.

What’s the one thing that can make Joan Rivers cry? A bumble bee…on her butt!

Why won’t Carol Burnett help Joan out at Cooper’s school function? The truth lies somewhere in Hawaii..

This season we’ve seen fights and infidelity, marijuana and tattoos, Vegas’ strippers and classic smotherhood moments, but that’s the Rivers – and WE love it.

In this deleted scene, we learn how Sabrina hustled her husband when they met, and how the proposal was all her idea.

Now, who wouldn’t pay to see Joan Rivers zip line in Vegas?!
