This one involves a bell, but no water. It made me chuckle but then my sense of humor is often dark. Enjoy (or not).

Guy walks into a church, climbs up to the belfry and runs face-first into the bell. It rings loudly, but he falls to his death. Police ask if anyone knows him and the reply is: "no, but his face rings a bell." Next day another stranger comes in, states it was his brother who died the day before, repeats the ringing and the fatal fall. When asked if anyone can ID him, the reply: "he's a dead ringer for his brother."
