This is another Monty Python reference I found.

What you do is go to jaitzo isle, find a tower with a gurd on top, right-click on it, and choose "watch shouting." It will show an entertaining clip, but especially, the neitiznot guard will shout "your mother is a hamster!" and the jaitizo guard will shout "your father smells of whiteberrys!" Both are insults used in Monty Python.
