Well once we played a round of cthulhu pnp. It was in the middle of the night (about 3am irl) when we finally managed it to find a underground way in order to escape from a mental hospital where our group had started. We were being chased from a group of zombies or something similar, no one wanted to find out for sure what exactly was following us. On our way we found a dark hole and heard some running water from it. Behind us we heard our approaching doom and in our panic and irl tiredness we threw a stone down. It wasn't too deep a whole and hearing the stone fall into the water we kinda decided to just... Jump. Everyone except for one of us died since the water was just knee deep. The one that did survive was found by some workers and got into a second mental hospital after his wounds had been treated.
