Barney and Friends premiered on PBS in 1992, starring Barney, a friendly purple Tyrannosaurus rex who taught lessons through songs. Its closing number, I Love You, was sung at the end of episodes to the melody of the traditional children's song This Old Man, with lyrics about family and caring. The tune became one of the most recognised children's TV songs of the 1990s. Online, clips are reused both nostalgically by viewers who grew up with the show and ironically in memes, remixes, and soundboard posts.
