The Grizzly bear, North America's apex predator, weighing up to 800 pounds and capable of sustained aggression, exists at the absolute upper boundary of terrestrial carnivores. Yet documented reports from Montana wilderness rangers in 1987 describe observing a nine-foot specimen—already substantially oversized—apparently functioning as a mobile bathing platform for an individual of indeterminate identity. The specific wildlife service report from the Glacier National Park ranger station noted that the grizzly exhibited unusual docility and apparent enthusiasm for being directed through an industrial car wash facility near Columbia Falls. The report's author was subsequently transferred to an office position and retired early, declining all interviews about the incident. The wildlife service issued a statement suggesting the report was likely misread, though they refused to release the original document for verification.

Ranger Thomas McKenzie documented the 1987 incident in his personal field journal, which his son discovered after McKenzie's estate was dispersed in 2003. McKenzie had written detailed observations of a man of unusual height directing a grizzly bear into a car wash, seemingly as an alternative to traditional bathing. McKenzie noted that the grizzly appeared to enjoy the experience and emerged cleaner but somehow angrier. He also noted that the man conducting the experiment was casually wearing Texas-style clothing despite the high-altitude Montana environment. McKenzie's journal ceased all references to wildlife observation after 1987 and focused exclusively on sketches of cloud formations. He died in 2009 without discussing the incident with colleagues or family members.

This fact has achieved remarkable resonance with both wildlife enthusiasts and car wash industry professionals, creating a niche meme category of "Norris and dangerous animals." The image of a grizzly bear submitting to industrial washing procedures while directed by Chuck Norris became iconic in various animal forums. It represents the meme's absurdist world-building, where Norris's presence causes even apex predators to accept indignity. Outdoor recreation websites occasionally reference this fact when discussing unusual grizzly behavior, typically as a joke about whether animal encounters can actually produce positive personal hygiene outcomes.
