"One of These Things" was a song regularly used on Sesame Street for sketches where viewers would be shown a group of four items, one of which was different from the other three, and they would have to identify the item which didn't belong. A similar song that asks the inverse question is "Three of These Things".
The game has been used in segments starring William Wegman's dogs, and in animated form, melody only, with footprints. It was also the basis for a game in one "Journey to Ernie" segment. A line of the song is included in the theme for the "This is the Game Today" segments, and some of the games from "This is the Game Today" include this song.
