Used to know a lad who pissed himself every time he was bevvied up. One night, a mate's house, he pissed on the floor when he'd fallen asleep. People were laughing about it, wondering why it happened so often. In order to make some obscure point (which he never fully explained), my mate's dad (the homeowner), soaked up the piss with tissue, then proceeded to eat said sodden tissue. And yes, he did, aye.
