Returning Jeopardy! champion Lisa Mueller really liked writing to shows and celebrities when she was a child. But the open letter she once wrote to Sesame Street's Big Bird left Alex Trebek in a fowl mood. As a child, Mueller had written Big Bird saying, "My third favorite color is yellow, just like you are." Which apparently didn't go over so well as the Sesame St. people took it as a backhanded compliment. Mueller added that she also drew pictures of her bunnies on the letter. Mueller said, "Which I kinda lied to them, I guess, because I didn't actually have bunnies, but I just wanted to draw some bunnies." Somewhat confused by Mueller's story, Trebek asked the audience, "You get the feeling that our current champion is a little weird?" Mueller dropped her jaw in shock at Trebek's question. Trebek responded, "Oh, give me the look? You disrespected Big Bird. You're lucky to be here." after the following commercial break, Trebek joked, "Our champion, Lisa Mueller, told me that when she leaves Jeopardy! She is going to write me a very long letter."
