Pissing with your trousers round your ankles
Back when I were a lad, it was unthinkable to go to have a wee-wee in the urinals and NOT drop your trousers and pants to the floor. Thus, if you were to wander in at playtime, chances were you'd see a row of pink, hairless arses, staring at you like so many fat ladies' faces. I have often been tempted to attempt this at work, but fear that the hilarity of the occasion would be marred by the inevitable whisperings about my obvious perversion and weirdness if anyone caught me.
