"Glee" gets the "Sesame Street" treatment (Video)

(CBS) Sesame Street is singing a "Glee-ful" tune.

The children's show paid homage to the Fox series in a segment about the letter "G."

Gleeks will recognize puppet versions of Mr. Schuester, Rachel Berry, the Cheerios and Coach Sylvester (in her trademark track suit, of course).

The clip is a lesson on the letter and "G" sounds, but it pokes a little fun at the show, too.

Watch the video above.
