In the US military, medical personnel prescribed motrin (ibuprofen) frequently and in large doses for any number of injuries or ailments. In the late 1980's and early 1990's before the generic version became available it was so popular that it accounted for almost 50% of military pharmacy prescriptions. The drug was coined the name "Vitamin M" due to its high number of prescriptions for US soldiers, sailors, airmen and marines.
Hey Boats, what did doc give you for your hurt knee?
He gave me light duty for a week, told me to ice it for 20 minutes 3 times a day, and take Vitamin M for 2 weeks.

The sudden impulse to turn around and smile at your friends the first time you fire a fully automatic weapon.

-This phenomenon also happens each time you shoot an automatic weapon larger in caliber than your previous experience.
Guy #1- Dude, I got to shoot a .50 cal for the first time today and I was all smiles.

Guy #2- Sounds like you couldnt hold back the machine gun reflex.
Guy #1- Well they say, "Happiness is a belt-fed weapon".
