It is an odd legacy from growing up in the middle of nowhere, with a lot of guns around, that my first thought after "What a moron," was, "He should have shot the gun, and then held the hot barrel on the wart to burn it off."

Not recommended as a solution to genital warts
Don't shoot off your wart to spite your private part, kids. [Image via Shutterstock]
