Star Wars on the Street Sesame Street : Season 13 Episode 58

Big Bird sees a flying saucer land in the yard behind the courtyard, and two metal men getting out. The adults just think it's his imagination, but are soon shocked when two droids from Star Wars (C-3PO and R2-D2) quickly shuffle (and roll) by. Things say that other things are small, but then something comes along that's bigger, or smaller, or whatever.
