Not to be confused with the old 1 or 2e story of infinite troll meat in a can.

Some madlad once built a precision steel canister with a screw-top lid. Then after hacking up some trolls he stuffed a chunk of meat inside and closed it up. Then for did he'd open the lid, wait a second for the meat to grow out a little, then slice it clean off right into the cookfire before screwing the lid back on.

Classic d&d trolls were never to be hacked to pieces without burning unless you wanted like 10x as many the next day.
