What's My Letter? was a Season 3 Sesame Street game show hosted by Guy Smiley. Prairie Dawn was the show's guest, and the object of the game was to guess a letter of the alphabet, given some clues. She manages to get the answer right when she hears the prize will be a mouse - which frightens her!
This was one of many tracks from the 1971 LP The Muppet Alphabet Album that was later recorded as a segment on the show, with the puppets lip-synching to the original album recording.
- Jim Henson puppeteered Guy, assisted by Caroll Spinney. Jane Henson puppeteered Prairie.
- Fisher-Price made a Sesame Street electronic game in 1995 called "What's My Letter?", inspired by this sketch.
