'Sesame Street' has become the latest hangout for 'Game of Thrones' actors it seems.
Earlier this week, actress Lena Headey stopped by the popular television show and teamed up with Elmo to teach kids the importance of relaxing.
But the fun didn't stop there for the 'Game of Thrones' cast.
Headey's co-star and brother on the award-winning show, Peter Dinklage, also got into the act with a cameo appearance Friday.
Dinklage's segment and subsequent song was dedicated to finding the meaning behind the game "Simon Says."
