A group of singing sewermen are doing it "Gangnam Style" in the sewers of London.
The Thames Water workers have released a YouTube video entitled Sewerman Style - influenced by Korean pop star Psy, whose song Gangnam Style has more than 900 million hits on the popular video website.
The new video urges people to not wash turkey fat down their sinks at Christmas.
Thames Water spends £12 million a year clearing sewer blockages across London and the Thames Valley with some instances causing sewage to back up into people's homes.
Singing sewerman and "chief flusher", Rob Smith, said: "Our video is a bit of festive fun with a very serious message. Sewer flooding results in people literally getting their own back. It's horrific. It's got to stop. That's why we're hell-bent on getting people to take heed of the sewermen's war cry: 'Bin it - don't block it'. Got it?"
Last year Thames Water were called out to 101 blockages on Christmas day.
The video features workers clearing sewers, dancing, and singing in their low-budget rendition: "If you flush it, then we see it, we really do, yeah, we really do".
