Speaking of wax rings, a really funny joke to play is to reverse the
piping in someones home, after it exits the water heater.

This way, all the toilets fill with hot water!

So, somebody comes in, takes a big dump, flushes.... and KABOOM! The
toilet explodes.

I saw this on candid camera a couple years ago.


Can't see it blowing up but I can guess they 'd have a sweaty butt!
