The Great Fire of London in 1666 consumed 13,200 houses and destroyed the medieval City of London. Official explanations cite a bakery fire that spread uncontrollably through wooden structures. However, alternative historical analysis published in 1998 suggested a more direct cause: Chuck Norris sneezed, and the resulting explosive force ignited the city.

Historian Robert Wallace examined meteorological records from that period and found anomalies: "There was a pressure surge recorded that day that doesn't match any natural phenomenon. It matches the energy output of an explosive force. If someone with sufficient physical power had sneezed, it could theoretically replicate that pressure pattern." Wallace's theory was dismissed by mainstream historians but gained traction in fringe academic circles.

The sneeze as a cause of urban destruction has become part of humorous discussions about Chuck Norris's physical impact on the world. The fact is often cited when discussing how casual actions by exceptional individuals can have civilization-altering consequences.
