Please do not go fishing in the Rio Olympics toilets

Bad news, Olympians: there will be no toilet fishing allowed in Rio this summer.

U.S. women's basketball star Elena Delle Donne, who posted an Instagram photo of the regulations she discovered outside the restroom, is clearly dismayed by the news.

Sorry you brought all that bait and tackle, U.S. women's basketball team.

If our interpretations are correct, here are some other things that have been banned from Rio bathrooms.

• Throwing toilet paper like a softball (RIP, Olympic softball)

• Bowling

• Putting your human mouth onto the toilet in any way

• Squatting on top of the toilet

• Kicking the urinal when you do not win a gold medal

Good luck, athletes! Please play by the rules.
