I remember the Lost Worlds of Zorandor to this day for "good storytelling"

The expression on everyones face when a character (and this quote was completely IN character) stands up and yells "I can't marry you! You're a Nignog!".

Silence...

Then outraged laughter.

I believe the GM had to be handed a glass of water to stop him choking.

So, were you choking or just trying not to laugh? ;-)
