No funny business: Sochi bathroom dos and don'ts

By now you've all seen the communal commodes. 

But in addition to the privacy issues, a Twitter post shows Sochi bathroom goers may have a whole other set of rules to contend with while doing their business.

This weekend, Canadian snowboarder Sebastien Toutant tweeted a photo from the bowels of a Sochi restroom.

The six-paneled placard illustrated five bathroom don'ts in addition to the proper throne-sitting do. 

Fishing, of course, is out.   

Bowing to the porcelain gods is verboten.

If the bowl squat is your jam, then you're out of luck.

The last square, however, is somewhat of a mystery. 

Is it forbidding needles when you've got a broken leg? Playing with toy zeppelins while attempting a half lotus?

Extra points if you can flush it out.
