The riff comes from “Bad to the Bone,” a blues-rock song released in 1982 by George Thorogood and the Destroyers. Its opening guitar figure became widely recognizable through repeated use in film, television, advertising, and popular culture. Online creators later matched the song’s tough attitude with skeleton pictures, animations, and game characters, creating an intentionally exaggerated joke. The combination remains useful because viewers recognize the musical cue immediately, while the skeleton imagery turns its swagger into visual comedy.
