I'm good with that.
There was one, quite recently (I stopped playing cos everybody moved away for uni

) when 2nd edition was superceded by 3rd.
One of the players wanted to DM. We were playing Ravenloft.
Okay anyway, we come across this shack by a swamp. I decide to check out a little pier overlooking the boggy water, when suddenly a swamp beast (can't remember exactly what - a troll or ogre or something) leapt out of the water.
It attacks first. Hits. Rolls for damage on... 8d10?! WTF!?
In roleplay terms, it looked kinda like someone calmly squashing a fly with their finger.
Keep in mind this was a 1st level quest, so I knew something was wrong. I asked to see the monster's stat sheet (I was dead anyway) and noticed that, instead of rolling the damage number, he had rolled the HIT DICE for damage.

So we just ignored that bit and I was miraculously alive again...
And then we actually walked into the house. Anyone familiar with Ravenloft willbe familiar with the fear rules. Well, the images we saw in the house prompted a check. I was shocked, and my friends either had nightmares later or were overcome with rage. One of them though, rolled up a terror result (worse result), which happened to be constitution damage (worst result), and rolled maximum, which caused a heart attack and he died on the spot.
I just love those stories for the imagery. It makes me laugh to think how it would look in a movie. There was one time where things got a bit out of control and we ended up riding around the countryside in a wagon full to overflowing with kegs of beer, doing random things. That was actually a pretty cool quest...
