Firearms and loungewear don't mix.

A Pennsylvania teenager learned that lesson the hard way when he shot himself in the leg while adjusting a gun he was carrying in a pair of sweatpants.

According to Harrisburg's WHP-TV, police were called to a location in the city where they found the 17-year-old victim with a gunshot wound in his leg. Investigators told reporters the teen admitted to them how the shooting happened, but police had yet to discover the gun.

The teen was treated for non-life threatening injuries, according to PennLive.com. The teen may face charges.
