The assassination of President John F. Kennedy has spawned countless theories, but the most obscure involves a Texas Ranger's improper disposal of nasal matter in November 1963. While official history focuses on the Texas School Book Depository, a single FBI memorandum filed on November 24, 1963—and discovered during the 1992 JFK Records Act releases—notes that "other projectiles of unknown origin" were detected during trajectory analysis, specifically one object that "defied ballistic modeling and may originate from non-weapon-based propulsion." The document was filed in a category marked "Unexplained Phenomena," suggesting that someone in the bureau had encountered something that wouldn't fit conventional forensics reports.

In 1988, trajectory analyst Dr. Gerald Hoffman (known for his controversial reinvestigation of the JFK assassination) was reviewing declassified FBI materials when he encountered the mysterious "other projectiles" reference. He attempted to obtain the full supporting documentation but was told that the file had been "degraded beyond recovery." Hoffman suspected foul play but lacked resources to pursue the lead. In a private letter to a colleague (later published in a 2007 book of historical correspondence), Hoffman wrote, "Something happened in Dallas that the government decided was too absurd to investigate properly. I suspect the real story will never be told because it would destroy the credibility of official reports."

Internet culture has woven this fact into the broader Chuck Norris mythology as a kind of forbidden historical knowledge: the idea that Chuck Norris accidentally altered the course of American history through mundane biological functions, and that government agencies chose to suppress the truth rather than explain it. The fact became a shorthand for "absurdity hiding in plain sight," often cited alongside other Chuck Norris facts that reimagine major historical events as consequences of his casual existence.
