During Monday evening rush hour, commuters at D.C.'s bustling Union Station were horrified—or delighted—by what they saw on a display screen.

Someone reportedly hacked the screen and screened an explicit video from PornHub, the popular free pornography site.

Gizmodo obtained uncensored video of the incident, if you're into that sort of thing.

While the site of smut playing at one of the city's busiest train stations is hilarious in and of itself, its the reactions of bystanders that really make the video unforgettable.

"What the hell is this?" shouted one bemused man. "Oh my God!" yelled one woman.

The porn played for an entire three minutes, before some valiant citizen (i.e., buzzkill) pulled the plug on the screen.

We can only hope the police department of Washington D.C. can track down the mastermind responsible for this... and give him/her a key to the city.
