First it was the strange double toilet, now we're getting a look at the rules in place for Olympic bathroom use.
Canadian snowboarder Sebastien Toutant tweeted out a picture that he took that appears to show picture of acceptable practices for those using washrooms in at the Olympics.
"Well that's interesting... Sochi rules in the bathrooms," wrote Toutant in a tweet from February 1st.
The diagram looks like it bans, among other things, drug use in the bathroom, and toilet fishing.
It's not the first time that toilets have drawn attention in the lead up to the Sochi Olympics.
A photo of two toilets side by side in Russia also caused a stir on social media.
