Once upon a time there was a village with a fat ugly whore who would suck and fuck anyone for 5 bronze shillings.
One day a wooden pair of skis with a splinter disguised themselves as a pair of brand new fibreglass skis, and sold his bindings for 5 bronze shillings. The wooden skis then took the 5 bronze shillings to the village whore.
Unfortunately the village whore did not know that the pair of skis she just fucked was actually a wooden pair of skis with a splinter. She did not realize that the splinter tore a hole in the condom and that she had just become pregnant with the future skierman. 9 months pass by and the most vile hideous half man-half ski creature/baby slid out of her stinky vagina.
That is the legend of how the half man-half ski creature skierman was created.
