I had a piss into a bottle the other month when it was really windy
I was stuck in a traffic jam on the M62 in the outside lane and it was dark and i was alongside an artic. I didnt wanna go walking all the way to the hard shoulder just for loads of people to watch me piss all over myself cos it was so windy, so i pissed in an oasis bottle (Wide neck ) and didnt spill a drop

Also (A bit different) i know someone who was pregnant and her waters broke in the passenger seat of the car on the way to hospital
Imagine buying that second hand
