I have had a lot of intentional ones and probably a few accidents in my youth. The only accident i can tink of as an adult, I had to take a drug test for a job interview. I was a little gun shy about so I consumed quite a bit of coke at lunch and didn't use the bathroom. I went directly from lunch to the clinic. For some reason the service was extremely slow that day even though I had an appointment. I thought would go in pee and leave I was in the waiting room for 30-40 minutes and all of the sudden I had to go bad, their was no lobby bathroom and the receptionist was away from the desk, so I couldn't just open the door to the examination area. I was holding myself like a little kid I decided to go outside and see if their was a gas station or something nearby. as soon as I got outside, the dam burst and I was hopelessly wetting my pants in the parking lot. Ok think, now what. As luck would have it I was only a couple of blocks from my parent's house. I knew I had some old clothes in the garage there. So I ran to the house and wouldn't you know it my dad's car was in the driveway. More panic but but little choices either. I had a key and went in, dad was working in the back yard, so I beelined for the garage found anther pair of pants, stuffed the wet pants and underwear away for later retrieval. Ran back to the clinic and went in they said they had called my name a few minutes before, I apologized and said I stepped out for a smoke. They said it was no problem and go on in. I was pretty much on empty at this point but managed to squeeze out enough to satisfy the drug test. No one seemed to indicate their was any knowledge of my accident. I did get the job too, doubt I would have if the report read clean for drugs, but applicant wet his pants in the parking lot
I got myself invited to dinner the next day at my folks house I still had some pissy pants there. And to my surprise my dad asks if I was at the house the day before. Though I got busted. I said I had a job interview and needed a tie that was in the garage, and used it as and used the excuse I had some other stuff out there I wanted to take home. The box with the wetties was undisturbed where I had left it. I just put the whole box in my car and no one said a word.
A huge and completely accidental public wetting and to the best of my knowledge no one knew.
