VIDEO: Peter Dinklage Sings on Sesame Street

Game of Thrones stars Peter Dinklage and Lena Headey managed to keep it very family-friendly on their recent Sesame Street appearances.

New season, new sexy stars. See our fall TV crushes! 

Though no one seems to pay attention to Tyrion Lannister's advice on the HBO drama, Dinklage finally got people to listen up as Simon of "Simon Says" — and he did it in song no less!

Headey, on the other hand, did the most un-Cersei Lannister thing possible — she relaxed! The Game of Thrones star helped teach the manic muppet Murray to chill a little bit, all with the power of words.
