Last but not least, our final Sesame Street Christmas concert guests are Big Bird and Cookie Monster! They will join Frozen’s Santino Fontana, and their Sesame Street friends Count von Count, Elmo, Grover, Abby Cadabby, Rosita and Bert and Ernie for the upcoming Christmas concerts, which will be held December 11-14, 2014.

Big Bird made his first Sesame Street appearance on November 10, 1969. He is an 8-foot, 2-inch yellow bird who has been known to ride a unicycle. He lives next to Oscar the Grouch in a large nest behind 123 Sesame Street. He has many talents including dancing and singing, which makes him a perfect fit for the concert with the Mormon Tabernacle Choir. Big Bird helps children know that it’s OK to not know everything. He often says, “Asking questions is a good way of finding things out!"

Cookie Monster also made his Sesame Street debut in 1969, but a few years earlier he appeared in snack-food commercial eating, you guessed it, cookies. When he eats, he makes a loud munching noise, which is interpreted as “Om, nom, nom, nom.” Some of his other famous phrases include, “Me want cookie, “ or “Me eat cookie.” His famous song, “C is for Cookie” is one of the most popular Sesame Street songs. Cookie Monster’s latest segment is called Cookie’s Crumby Pictures, which parodies popular movies. In these segments Cookie Monster serves as the spokesman for self-regulation.

Here are some of their videos below, beginning with Cookie Monster's Hunger Gamesparody.
