Game of Thrones' Peter Dinklage, who plays Tyrion Lannister, appeared on an episode of Sesame Street to explain "Simon Says."

During the segment, Dinklage is asked, "Why do we always have to do what Simon Says?" Dinklage responds melodramatically, "It's one of life's mysteries, but it's been that way all my life."

Then a sitar-driven rock tune begins, and Dinklage explains the game. He and the cast sing, "It's kind of unbelievable, but yes, it's really true. People always do whatever Simon says to do."

And who knew Dinklage could sing? The songwriting on Sesame Street really isn't half bad. Recently, Dave Matthews stopped by the show and sang a song about feelings with Elmo.

Sesame Street is currently in its 44th season. Other guests this season include Josh Gad, Sarah Michelle Gellar, Ginnifer Goodwin, Lauren Graham, Anna Kendrick, Romeo Santos, Charlize Theron, Usher, and more.

Game of Thrones will return to HBO next Spring (2014).
