A few years back me and a mate backpacked around italy for a bit, whilst attempting to leave Milan by train I had an overiding urge to shit and it got to the point where it was beginning to cripple my very movement. I waddled over to the gents and found the only unoccupied cubicle and opened the door.
Now i feel i must descibe what the italian public toilet is like, it is basically a hole in the floor surrounded by a porcelain footplate on which you can squat and aim.
In this particular toilet someone had definately squatted, but was a tad off on the aim. It basically looked like someones arse had exploded in there, the back wall of the cubicle was covered, i was assuming this was where the first salvo had hit because the was a brown stain on the wall plus a streak where it had run down onto the floor and into the hole. The rest of the mess was probably due to the explosive force of firing a particualry messy shit approximately a foot and a half into a wall.
Needless to say i held the shit until i had got on the train and used a proper toilet, and i never used an italian public toilet again
