I parked my dad's truck in the backyard once when I was a teenager. Obviously, I'm not that clever, so I will use DH's.
I mentioned him dumping elephant poop on a coworker's car from an overpass in another post. There was also the dead fish he put in a glove compartment on a hot day of another coworker. That cop jacked DH's truck up just enough so that his tires were off the ground, but he wouldn't notice. So when he tried to back out of his spot, he just spun and spun.
What are some of yours???
