The line began as the closing sign-off for Warner Bros. Looney Tunes and Merrie Melodies cartoons, delivered by Porky Pig at the end of the short. Porky, who first appeared in the 1930s, became closely linked with the phrase, and repeated television broadcasts kept it familiar to generations of viewers. As cartoons moved online, creators began using the clip as a ready-made ending for videos, memes and compilations, borrowing its instant recognition. It remains popular because it signals a clear, friendly finish in just a few seconds.
