When you shoot a gun drunk, you get results. Large, gaping results. Whether you are blasting gin bottles off the roof of a junked Camaro or simply getting the cat out of the tree, squeezing the trigger is a wonderful way to cut loose.

A drunk staggering down the street with a gun is alarming. Having access to a weapon while tossing back beers allows drinkers to come up with bold new solutions to problems.
