I think it's time Jub proposed a new game: every time a character (PC or NPC) tells Brutrumukk not to do something, they put a copper piece in a jar. If Brutrumukk doesn't do the thing, he gets to keep it, but if he does do the thing, he has to give it back. This might be the only way Jub can teach Brutrumukk to have a little self-restraint.
