There are three times that have been funny - the rest not.
The first time was right after getting out of the hospital. My daughter took me to lunch and we were sitting in a booth. My bag started growing and growing and finally was sticking straight out and looked like a blimp about to take off. I couldn't get out of the booth. My daughter helped me wrap my coat around my middle and we finally were able to work me and my bag away from the table. Once in the car, my daughter (a nursing student) asked me if there wasn't some way to "burp" the bag. I responded that yes, I could do that, but I wouldn't recommend it in a closed car. She condescendingly informed me that she had experienced much worse things than the smell that might come from the bag...so I let her rip...and my daughter started yelling to open windows and doors.
The second time was in the hospital - had been readmitted for some tests - and the "hospitalist" came by to check me out - he pulled my gown down, which caught on the edge of the bag, which then, of course, pulled off. Diarrhea spurted across the room, hit the doc on his beautiful white coat. He paled, ran out of the room and the nurses and I rolled in laughter as we were cleaning up the mess.
The third time was in a bathroom in an assisted living facility that my mother lives in. I could feel the bag filling up fast, so excused myself and went to the bathroom. Normally I carry at least one extra bag, cleaning cloths, etc. But that day I had just brought my wallet. I was right, the bag was full and the diarrhea was still coming. I tried putting toilet paper over the stoma to plug it (which, of course, didn't work) while I tried to empty the disposable bag...then flushed the toilet which backed up and spilled all over the floor...so there was shit floating in the water on the floor, I'm still having diarrhea and I have to figure out how to get someone to help. I grabbed my jacket, put it over the whole mess on my front, ran to the front desk and yelled for help. Ran back to mom's room, where she is sitting smiling - didn't realize anything had happened. I left immediately, tried not to get any of the poop on the car and, like others, ran inside to the shower clothes and all. Turns out mom's roommate tried to flush a disposable diaper...
There have been other times that have not been so humorous...but I try to remember that everyone has something they have to deal with. I sure have become more compassionate...
The ones I hate the most are during the night in bed. I actually started wearing a belt to bed so I wouldn't pull the bag off in my sleep.
