It was just last year during the TP shortage. I decided to buy a bidet to make me less dependent on TP, and because I have heard how nice it is to the "swampy butt" alternative that sometimes plagued me.
I had never used one before prior to buying mine, so I tested the water pressure out like how most normal, sane people would - slowly turn the knob until you feel like the pressure is enough to get the cleaning done.
My wife's brother and his wife come over to hang out the next day, and she needs to use the toilet immediately when getting there because they had McDonalds for breakfast earlier that day.
I told her about the bidet and that she doesn't have to use it - just do her business how she normally would. She said she wants to try it because she had also heard how well they clean.
She goes to the bathroom.
About 10 minutes later we hear a loud painful scream, and she comes from the bathroom crying and laughing at the same time, and then drops to the floor in our hallway - rolling with her fully exposed butt cheeks conpletely tensed up. Her husband and my wife go running up the stairs to make sense of what what going on, and the water was still spraying from the bidet up nearly to the ceiling at FULL BLAST! She didn't ease into it - she just let it ride, and she regretted it.
She eventually regained herself, but spent the rest of the next week or so pretty sore. She went in to see a doctor, and was told she had a small fissure in her anus as a result.
We all still laugh about it, and they have actually purchased a bidet of their own since then. 🤘
