Ellie and Burt made friends very quickly. She asked him if he was really Burt from Sesame Street or if he was a person dressed up like Burt. He kept shaking his head no that he wasn't a person dressed up like Burt, but she didn't believe him. She said, "I know you are a real person in there, but I don't care...your still Burt". LOL. She's so smart...I love how she knows the truth but still gets caught up in the fun.
