Just before my first born arrived I was out for a run, about a mile from home the pressure started, released a few test farts to see how serious the situation was whch eased the pressure a little. It soon became apparent there was now no room for pressure release and the next push was going to be serious. I hobbled walked, limped, minced my way home and about 100 yds away it fell out. Completely filled the inner liner in my shorts as I didn’t have underwear on and it swung between my legs as I walked.
When I eventually reached my front door, with the package precariously balanced between my legs, I noticed we had a visitor. Entered the front room gingerly and sat on the sofa with my pregnant wife was the woman who comes round to sign you up for nappy trials! I shuffled upstairs to the bathroom and locked the door, drooped the shorts slowly, emptied into toilet, rinsed inner liner, and then bagged them and put to one side for a wash as soon as visitor had left.
I later found out that a neighbour had seen me making my way home and asked my wife if I was ok as I was walking like I had just got off a horse!
Never done it at work though.
