The rules of beer pong vary from region to region—Is blowing allowed? When can you rerack the cups? What should we pee on and whose dad is getting us all jobs after graduation?—but it’s universally understood that defenders should create a distraction while their opponents are shooting. That distraction probably shouldn’t be a gun, though.

A Chicago-area man is charged with recklessly discharging a firearm after he started waving a 9mm semiautomatic around during a Fourth of July beer pong match, DNAInfo Chicago reports. Manus Shannon, 27, was apparently trying to distract his opponent, but accidentally fired the gun when the other man pushed him away. He hit the opponent in the finger, and another man who was texting nearby—and wasn’t involved in the pong game—in the shoulder.

The victims drove themselves to a nearby hospital and are in stable condition. Shannon is being held on $100,000 bail and, depending on local regulations, may be required to drink one cup of beer due to an illegal block.
