The 10 Best Celeb Cameos in Famous Sitcoms, Ranked

Let's take a look at those unforgettable celeb cameos:

At the top of our list, we've got none other than Joe Biden, who graced "Parks and Recreation " with his charm, turning Leslie Knope's dreams into a hilarious reality – twice! Then, there's the ever-eccentric Kesha, causing a ruckus as Jane's neighbor in "Jane the Virgin," perfectly embodying the life-of-the-party rockstar next door. And who could forget the surreal combo of Rob Thomas and Sinbad in "It's Always Sunny in Philadelphia"?

We've got Prince charming his way through "New Girl, " giving out life and love advice like the pop royalty he was. And, of course, The Rock flexing his acting muscles in "That ‘70s Show," cleverly nodding to his wrestling lineage. Katy Perry brought her signature blend of sweet and silly to "How I Met Your Mother, " while Carrie Fisher's memorable turn in "The Big Bang Theory " had her wielding a bat with the same gusto as a lightsaber. From Brad Pitt's comedic genius in "Friends" to the vampiric council meeting of the ages in "What We Do in The Shadows," these cameos are nothing short of sitcom gold.
