Peter Dinklage has one awesome set of pipes.

The "Game of Thrones" star showed off his singing chops when he made an appearance on "Sesame Street" Friday, breaking out into a catchy tune about the game "Simon Says."

The Emmy winner was joined by a few Muppets to help him sing the song, which explained the rules of the game.

Dinklage is the second "Game of Thrones" star to hit the show this week, with his co-star (and on-screen sister) Lena Headey popping up on the show that day as well.

In Headey's skit, the actress teamed up with Murray to teach him how to relax.
