Check out this video of Peter Dinklage ("Game of Thrones") singing with the Muppets on Sesame Street. Because why not!
In the charming song, Dinklage and his felted, furry friends try to get to the bottom of why everyone must do what Simon Says. Dinklage has an apt quote for the situation: "It's one of the great mysteries, but it's been this way all my life."
