We all mess up every now and then — and that’s totally okay. But someone is probably getting fired for this mistake.

Thursday night at 11PM EST, some unsuspecting viewers getting ready for a brand new episode of Anthony Bourdain’s Parts Unknown on CNN were surprised to see that scheduled programming had been replaced by 30 minutes of adult entertainment.

The mess-up only affected viewers in Boston, as CNN’s broadcasting in the city is provided by RCN, a local television provider. Despite the channel sending through the correct video signal, but somehow RCN managed to press the wrong buttons and provide viewers with something quite different.

Twitter user @solikearose couldn’t wait for the latest episode of the popular travel show, but was shocked to find explicit material on her screen when she tuned in.

I can’t wait until @RCNconnects wakes up tmrw & realizes that hardcore porn was broadcast on @CNN instead of @PartsUnknownCNN tonight

It’s likely there’s a simple explanation for the mix-up, but until we know what happened it’s hard to see how someone could mess up this badly – and not notice for a full half an hour. Luckily it was past bedtime for potential underage viewers, but that probably won’t save someone at RCN from getting yelled at today.
