When I was in my early 20s, I went to visit my buddy and some doosh in a pickup truck decided to park diagonally across two parking spots. The lot was completely full and I had to wait until somebody left to get a spot.
After we parked, my buddy and I went over and jammed a stick into the valve stem of both tires on one side so it would release the air. By doing two tires, I knew he would have no chance to just throw on a spare.
Only wish I could have seen his face when he saw his pickup listing hard to starboard.
When I was just learning to drive, my sister and I would drive to school - but we had to park on the street in the city - and every day finding a spot was like a 30mins exercise.
One day, I found a spot near our house and my sis dropped me off to hold the spot (there were cars behind her so she could not back up) while she went around the block.
After she left some douchey-looking guy in a custom-painted GOLD VW Jetta nosed into the spot and actually came right up to my legs and bumped me with his car. Like a naive kid I was explaining that I was holding the spot - he was like a 30yr-old - gave not a fck at all - and hopped right up the brownstone steps in front of the spot and into his apartment.
I was so angry. I went down to the corner and bought a few tubes of crazy glue and went home. I waited until it was dark and then came back to the street, cut off the tops of the crazy glue tubes and emptied them into the door locks on either side. This was in the 'old' days before keyless entry.
I hope the douche enjoyed his convenient spot. . ..
