You probably know that John Mulaney is hilarious [1], but you might not be aware that he's actually got some pretty good dance moves. On March 3, he showed off his skills on Saturday Night Live [2] during the "Cha Cha Slide" skit. In the segment, Mulaney plays a software engineer attending the wedding of his girlfriend's cousin. Although he appears nervous about being at the event, he seems pretty comfortable on the dance floor [3] when everyone starts doing the Cha-Cha Slide with Kenan Thompson as the DJ. Not only does he have a mean salsa sway, but he impressively hits Beyoncé's signature move from the "Single Ladies" video [4]. Watch him move and groove in the clip above!
