Truthfully now, have you ever?

I was on YT the other day watching Margaret Cho stand up. There is __lots__ of it, and she is very good. One bit was kinda icky, but trust Cho, pretty funny. It was about being on a diet which affected her digestive order. She was in traffic, and had to go, right away, with nowhere to stop.
Happened to me.
I was on my way to see a relative in Utah, and I was unprepared for the incredibly long stretches of highway with no place to stop, or even pull over. I had no choice. I reached for a beach towel, which hit the first trash can I came to.
Am I the only one besides Margaret who has experienced this trauma, or have some jellies been there too?
