A virile young man
A virile young man went to his friend, a pharmacist, asking for some Spanish fly because he had two hot (very, very hot) dates that night and didn't want to disappoint them
The pharmacist told his friend that he could not give him the Spanish fly, it was illegal, and he could get in much trouble for it
The young man begged and begged, and finally his friend gave in and supplied him with some Spanish fly.
The next day, the young man entered his friends pharmacy looking mighty tousled and worn out
The pharmacist said, "You look terrible! What happened?" His friend then dropped his pants to show just how terrible he indeed looked; his privates were bruised, swollen, and generally abused
The young man moaned, "I need some Ben Gay"
The pharmacist exclaimed, "Ben Gay! You can't put Ben Gay on THAT!"
The young man then said, "I know, I need it for my arms, the girls never showed up"!!!
