WD40

WD40 is called WD40 because it was the 40th water displacement formula that the developers tried, and the first one to work.

This is true.

http://en.wikipedia.org/wiki/WD40

"WD-40's name comes straight out of the lab book used by the chemist who developed WD-40 back in 1953. The chemist, Norm Larsen, was attempting to concoct a formula to prevent corrosion — a task which is done by displacing water. Norm's persistence paid off when he perfected the formula on his 40th try."
