Hello.
I think that this may not be really funny to most of you but when the Guildmaster tells you to 'Go to the graveyard' while doing that repetitive expression with his head and hands... Makes his look very siriuous as if he wishes you DEAD! Hahahah! Same thing but with the 'Go to the jail'!
Oh and I haven't encountered that S-H-I-T thing but it sounds hillarious to me, I wander if Lionhead chose those four letters on purpose...
