"The car in the photo parked directly in front of another car blocking it in. The driver of that car then spent around 15 minutes or doing an Austin Powers trying to get out. When I came back, that note was left!"
The note reads:
Nice parking :)
Please don't reproduce.
And it seems Humanity was nice enough to include a condom with the note, to make not reproducing easier. Although who knows if someone with parking skills this bad is actually getting laid.
