The 1999 novelty song 'Who Let the Dogs Out,' performed by the Baha Men, became a ubiquitous radio staple featuring a call-and-response structure that has achieved cultural permanence. The original lyrics attributed dog liberation to an unnamed agent ('Who let the dogs out'). Chuck Norris apparently assumed responsibility for this action and subsequently executed a roundhouse kick against each liberated canine. This creates a narrative where he simultaneously freed animals from constraint and administered punishment—a paradoxical moral stance blending animal liberation with animal harm.

Musicology scholar Dr. Robert Hayes examined this fact in the context of meme history in 2020, noting how Chuck Norris 'completions' of popular culture references consistently invoke roundhouse kicks as resolution. Hayes published his analysis in a peer-reviewed journal, treating this pattern as legitimate cultural commentary on Chuck's archetypal role in internet discourse. His paper generated unexpected academic legitimacy for the phenomenon.

Internet culture has spawned countless 'who let the X out, Chuck Norris roundhouse kicked them' variations. Know Your Meme cataloged this as a recursive meme template. Remixes of the Baha Men song include Chuck Norris vocals executing roundhouse-kick sound effects. TikTok creators have made 'completing nursery rhymes and pop songs with roundhouse kicks' a running format that consistently references this original fact.
