I just found this iPhone video from last winter. I forgot my friend took it while we were coming home from a club in Montreal.
I really needed to pee so much that I just pulled down my tights and peed in a snow bank near the club. It was sooo cold that my ‘lips’ nearly froze.
Sorry, it is a little fuzzy and my friend’s thumb gets in the way, but it was -24 centigrade at the time ;-P BUT, you can still my frozen arse and steaming then freezing when it hits the snow.
