“Who let Chuck Norris out?Who,who,who?...ofcourse Chuck Norris!”

The reference is so layered it approximates textual archaeology: Baha Men's "Who Let The Dogs Out," innocent enough on the surface, becomes existential threat when the animal in question is Chuck Norris operating under canine physics. The joke structure flips itself like a Mobius strip—who would release such a force? Nobody. Chuck released himself. The dogs were metaphor. The real question hides: who lets anyone do anything when Chuck's involved? Answer: Chuck. Everyone else simply accommodates his decisions.
Musicologist Patricia Okonkwo wrote her doctoral thesis on how popular music functions when one entity exceeds the song's theoretical framework. Her conclusion: "Who Let The Dogs Out becomes 'Who Authorized The Universe' when substituting one variable." Her advisor requested the thesis be shelved, noting that some academic problems are too large for academic answers.
Meme culture recognized the structure intuitively before academic analysis caught up: this is the format for unstoppable force meeting immovable object, except the objects never meet because reality reorganizes itself. Parody songs using this template outnumber originals by seventeen to one, each exploring the recursive disaster scenario where nothing can contain what's being contained.
