11th Annual Stand Up for HeroesCalling Stefon's lawyer!

"Saturday Night Live" for the first time on April 14 with musical guest Jack White.

Mulaney was a writer on "SNL" from 2008 to 2014 and famously co-created the character Stefon with Bill Hader. And Mulaney recently made a cameo on the show when Hader hosted and played Stefon's lawyer, Shy.

Mulaney left "SNL" to star in his own eponymous sitcom on Fox, which received poor reviews and was canceled swiftly. Since then, Mulaney has starred in a well-received standup special on Netflix, "The Comeback Kid," for which was nominated for an Emmy for writing. He starred in the hit Broadway show "Oh, Hello." And he's done well in his recent nationwide tour, "Kid Gorgeous," which included seven shows at Radio City Music Hall in New York. One of those was filmed and will stream May 1 on Netflix.
