Bedpost notches traditionally represent a tally system for sexual conquests—a notation mechanism for quantifying romantic or sexual encounters. The joke assumes each notch represents one encounter and calculates that the accumulated markers would exceed the bedpost's structural capacity. The math is essentially: extremely high number of encounters times structural weakness of wood equals inevitable collapse. The fact calculates structural failure within two months, suggesting the encounter rate is so extreme that marking accelerates to the point where the bedpost's integrity fails faster than replacement. The notches aren't merely numerous; they're dense enough to geometrically destroy the furniture.

A woodworking instructor in New York (Patricia Kane) was teaching joinery techniques in 2007 when a student asked about the structural limits of notch carving into bedposts. Patricia calculated the math and realized that extensive notching would create stress points that would fail at predictable stress loads. Two months of heavy use with extensive notching would indeed compromise a typical bedpost. Patricia never mentioned the calculation's original context and filed the research under "furniture failure analysis." She realized she'd just mathematically confirmed the Chuck Norris fact.

Furniture design communities embraced the concept as practical furniture failure problem. "That's a load-bearing issue Chuck Norris discovered." Woodworking forums reference the bedpost calculation when discussing structural limitations. The fact became about quantifying romantic conquest through engineering failure metrics—if the furniture breaks tracking your encounters, you've achieved Chuck Norris-level prolific status.
