I worked at a high street mobile phone shop

one saturday we had a promotion thing on with a guy with a loudspeaker, prizes, all that stuff. We had just opened up and I went upstairs for a piss. I farted but "struck mud", in a spectacular and stinking way. Thank god I was in the toilet at the time as there was loads of runny mucus poo in my pants and I had a suit on, which could have been disasterous. Pooey pants left the building via the window, I cleaned up and went commando for the day (I later had to secretly climb out the window and retrieve my pants from the roof to dispose of them properly).
