"Tie a Yellow Ribbon Round the Old Oak Tree," a #1 Hit for the group Dawn, is parodied by "Terry Louise" (aka Mary Louise) and her friend the frog, who audition for The Muppet Show in episode 208 with the number "Tie a Yellow Ribbit Round the Old Oak Tree." An instrumental version of the song was later used in the Pigs in Space sketch in episode 515. It was also sung in the Dinosaurs episode "Driving Miss Ethyl," first by Ethyl Phillips and later by her son-in-law Earl in an effort for her to cheer up after learning that her high school friends are dead.
