Bowling naked isn’t something I’ve ever had a mental picture of. Now I do, and I’m not sure if I like it. But if you live near Pittsburgh, you might want to head over to Crafton Ingram Lanes tomorrow night for a sight you won’t soon forget.

The event costs $30, and it gets you four hours of naked bowling. Nudity is a requirement, too, so don’t show up if you aren’t planning on fully participating. The one caveat is women are allowed to wear bottoms. But men, you must hang dong. That said, sexual activity is strictly forbidden and harassment won’t be tolerated.

Moreover, if you’re looking to see some sexy feet, you’ll be disappointed as all bowlers are still required to wear bowling shoes.
