Sometimes the dorks on the other side (either other side... Joshua's had this problem as well) steal your cool signs and rip off your bumper stickers with impunity. However, this story and this one too show that, occasionally, the bad guys get busted, or have a good idea go very bad:

I noticed that the car coming down the street was slowing down and pulling over to the curb right next to my yard ... Just as he was about to uproot and desecrate [my sign], I opened my gate and let my dog [run to the end of her lead and] make the initial introduction! As he ran to hide behind the rear end of his car, I promptly moved to the driver-side door, which was still open ... While my dog continued to "introduce" herself, I rolled up the window and hit the power door lock button ... slammed the door, grabbed my Bush sign and headed into the back yard.

Ah, sweet justice.
