Sochi Bathroom Signs Forbid Fishing, Upper Deckers In Olympic Toilets (PHOTO)

You'd think this would go without saying, but you'd be wrong, apparently.

Some of the bathrooms at the Sochi Winter Olympics reportedly have signs that forbid vomiting and fishing in the toilets. The signs also appear to frown upon drug use and "upper deckers," a nasty prank we don't endorse either. (Some readers have pointed out that the symbol may also be encouraging those more accustomed to a squat toilet to keep their feet on the floor. But please, no upper deckers, either.)

A photo of one of the bizarre signs was tweeted by Canadian snowboarder Sebastien Toutant on Saturday.


So, to recap: no heroin, upper deckers, vomiting, fishing or peeing on the lid, but pooping side by side is totally cool.

This post has been updated to account for the 'squat toilet' interpretation of one of the symbols.
