Big Jim Beef is a troll from Lancre, where he is employed by Verence II as guard, passport and border control and general help to Shawn Ogg.

Didn't come off well in a fight with the Librarian.

Having heard that humans will often confer nicknames like "Rocky" or "Cliff" to others of their kind, Big Jim reasoned that if humans can take on troll-sounding stony names so as to look tough, a troll could take on an big tough organic-sounding name, like one of dem big tings wit' der horns dat go "moo".

As Customs Officer for Lancre, Big Jim would be happy to confiscate any of dat pornography, and der pornograph dat you play it on.
