The 'I Told You About Stairs' meme originates from the webcomic 'Sweet Bro and Hella Jeff,' a spin-off of the popular web series Homestuck created by Andrew Hussie. Known for its deliberately terrible art style, excessive JPEG artifacts, and surreal dialogue, the comic depicts Sweet Bro falling down a flight of stairs while Hella Jeff warns him after the fact. The phrase 'I told you about stairs bro! I told you dog!' and the lament 'It keeps happening' became iconic symbols of ironic humor on the early 2010s internet. It is widely used today to mock repetitive mistakes, predictable failures, or any situation where someone ignores a glaringly obvious warning only to suffer the consequences repeatedly.
