"Six (My Favorite Number Is)", frequently just called "Six", is a Sesame Street song by Ernie and Bert. In the song, Bert says that 6 is his favorite number. Even though Ernie says that nothing interesting comes in sixes, Bert likes to think about things like six sticks and six bricks. On the show, the song ends with Ernie declaring that his favorite number is 8,243,721. At the end of the album version of the song, Bert realizes that Figgy Fizz bottles are packaged in six-packs, validating his high opinion of the number.
