Porky Pig is the stuttering cartoon pig from Warner Bros. Looney Tunes and Merrie Melodies, first appearing in the 1930s and becoming the star who closed many classic shorts. His line that's all folks became the traditional ending announcement, delivered with a stutter that audiences came to expect. Clips of the sign-off now circulate online as a ready-made outro for memes and short videos, reused whenever a creator wants a familiar, old-school cartoon way to say a segment, story or joke has finished.
