.40 cal

A .40 cal is not a big fucking gun, it's an improved version of the 9mm. What it really is is a 10mm bullet, and packs more punch than the 9mm, but still allows for the same (high capacity) amount of rounds to be held in a clip. A favorite of drug dealers.

wd 40

Genesis of WD-40 "Water Displacement 40th attempt. Successful" As stated years ago by a representative of the manufacturer on CNBC. Comes directly from the procedural notes of the experimenters and how they referred to the final formula, which indeed does displace and protect against moisture.
Apparently the previous 39 formula attempts were not charted as successful.
