Actually the coolest thing about augury and divination is the temperment of the god being asked the questions.
The players were confronted with an artifact device that was generating a huge (1000 miles long) field of force dividing the land. When they finally find the machine they decide to use augury to determine whether it would be good the just trash the thing. There's two clerics, one of sky and one of magic. They ask the magic one. Well, destroying the artifact increases the net magic in the world (moves us from 2e to 3e.) So of course the magic deity says breaking it is a good thing.
They break it, lights and sound and much ado later I say 'Okay, that's the session guys, convert the characters to 3.0 for next time." (I had said it would be a few months before we converted before game started.)
I imply they may have asked the wrong god. They ask the sky god's response, which is "read book below stairs". This book explains how to shut off the force field without destroying the artifact. The look on their faces.
