WATCH: Bob Saget Joins Kelly Clarkson For Epic Medley Of Sitcom Theme Songs

For the season two premiere of her talk show, Kelly Clarkson stirred up all kinds of nostalgia! Kelly opens each show with a segment called 'Kellyoke,' and pulled out all the stops for her performance today (9/21).

This Kellyoke segment wasn't just one song. It was a medley of FOUR songs - all iconic sitcom themes! From Cheers to The Golden Girls, Kelly, of course, slayed each song.

I was NOT prepared when Danny Tanner himself joined Kelly for one of his trademark inspirational dad talks after her performance of the Full House theme song, "Everywhere You Look."

It's impossible not to smile (and sing along!) when you watch this!

Kelly is obviously obsessed with Full House: earlier this summer, John Stamos joined Kelly for a virtual duet of Kokomo! Watch it here!
