For me it was during a parade.
I was on a 911 medical emergency. After 10+ minutes taking care of the patient and getting them ready to go to the ER, I bent down to grab some equipment and wham, I felt it starting to drop out of my ass! I yelled to my partner that I’d be “out in a minute, I’m having a GI emergency”.
I used the bathroom in the house as quickly as I could take care of business. Luckily, the patient was stable and not in a serious situation.
