While adult theaters are still around, the desire to jerk it in public isn’t as common as it once was. The advent of better home theater systems — and, eventually, smartphones — means that you no longer have to buy a ticket and sit next to a stranger to watch someone get railed.

One of the many issues with running an adult theater, besides simply being gross, was having to deal with the mess of the dozens of men making sweaty spaghetti in their seats. As a result of the difficulty of constantly cleaning the place, many didn’t do it as much as they should have, a grand tradition that YouTuber Dan Bell shows is continuing to this day.

Starting at around 3:30 into the video, he begins shining a blacklight on the booths. What we see isn’t surprising, but it is gross. Every booth is a splatterhouse of jizzum, with dudes apparently just dropping loads on the walls, zipping up and going back to their wife and kids without even bothering to towel the whole thing off.

Commenters on YouTube appreciated Bell’s bravery for this endeavor. “If those walls could talk they would beg for demolition,” joked a user. “I never thought a brief camera pan into an empty booth could make my fight-or-flight kick in,” added another.

Thank goodness those days are behind us — and we’re well in the era of the Goon Cave.
