Not an evil deed of mine but of a friend of mine,during one extremely cold winter three friends set out to do an ice climb in the lake district these are done during the wee small hours when the ice is in good nick.
The first pitch was easy so it was free climbed , but for safety each person ascended after the person in front had reached a large ledge. With two climbers on the ledge one of them in need of a toilet the third set off only to pull up over the edge faced with a large arse mid movement glinting in the moonlight, and the other climber convulsed against the rock and ice tears rolling down his face.
I suppose when you have go you have to go.
