Sesame Street (1969)

Season 38: Episode 5

Elmo wants to play tag, but Zoe wants to play checkers. Alan notices them arguing, and suggests they play the "letter P game." In order to play, they need to look around the store for things that start with the letter P, such as pickles. While Elmo and Zoe have difficulty looking for P words, a penguin (who pronounces his p's hard) comes in and orders a peanut butter sandwich on pumpernickel bread, with a slice of pineapple, and a potato.
