I saw the most hysterical sign vandalism today.
I live near Pella, and there are signs extolling the virtues of the town for miles in every direction. Some devious individual took some spraypaint and painted away the "a" and modified the "P" to look like and "H". Net result, Pella -> "Hell" - ROTFLOLPMP!!!
To really put the jalepeno on the nacho, there's a song by one of my favorite metal bands (Benediction) entitled "West of Hell". Guess which direction I live relative to the town in question? Bwahahaha!
