For Jimmy Fallon‘s debut as “Tonight Show” host, there was a bit about his “buddy” who bet him he’d never host the long-running late-night show. Fallon tells this unnamed buddy to pay up, and then a cavalcade of stars proceed to file out onto the set and pay him the $100 they owe him — Stephen Colbert absolutely won the bit when he paid Fallon with a bucket full of pennies and then yelled, “Welcome to 11:30, b****!”

And just like when Fallon’s predecessor Jay Leno took his bow 10 days ago, Kim Kardashian got in on the fun. The star of “Keeping Up With the Kardashians” — which is owned by NBC Universal, in case you were wondering why she was there — was busy Instagramming some backstage pics.
