Sesame Street (1969)

Season 16: Episode 74

Big Bird fantasizes about Maria and Gordon vanishing through impossible means—Maria swimming the Atlantic and Gordon catching a rocket to Mars—in order to teach subtraction. When reality returns and they're actually gone, Bob becomes confused by Big Bird's mysterious talk of his imaginative scenario. Maria later receives a handmade flower from Big Bird that lifts her spirits after a long day fixing a grandfather clock. Sponsors: M, N, 9
