Ah, that brings back fond memories of the rental house in State
College PA (aka Penn State) with the Baptist church next door. We didn't prank them too
much but we were the first to appropriate the "Reserved for the Pastor" parking sign that naturally ended up on one of our porcelain thrones. It was replaced a few more times and even set in concrete before they finally gave up. Even we were impressed when someone took the concrete one.
One fine sunny Sunday morning I was making my donation at said throne listening to the music and choir as usual. Suddenly I heard an upstairs window open and for the next couple of minutes enjoyed Kenny's hilarious and entirely tongue in cheek rant about the noise and trying to sleep off a hangover. It was apparently loud enough that they closed their windows after that.
