"trust me!" said my mentor, hanging a boiled potato from a string. "certainty is the crucial point to do any chaos magic, even beginner ones like the one I am teaching you right now. Now, stand on your head."

"what?!" I asked, frowning. "how is that going to cast a disassembling spell?"

"just do it! But be certain that it will work."

"but it obviously won't!"

"okay, I'll demonstrate."

The old man stood on his head, hit a tree with a frying pan, took out a pair of socks and put a ball in it, smelled a rock, read the cover of a novel, took out a spoon and dug a hole, buried some ham in the hole, threw a chess piece in the air, licked a ladder, and poked himself in the armpit with a stick,all whilst having a serious expression on his face.

Then sent a giant volley of black fireballs towards a target, obliterating it while I stood there both shocked, impressed and confused.
