The Stanley Parable began as a Half-Life 2 mod in 2011 before its expanded remake in 2013, built around a narrator who reacts as Stanley disobeys his story. The Adventure Line appears as a yellow line meant to guide Stanley back on track, but he follows it into new chaos instead, with this jaunty theme underscoring the rebellion. Clips of that scene spread through gaming videos and edits, and the music became shorthand for gleefully abandoning instructions and treating a detour as the real adventure.
