Conspiracy Theorists

This morning, as I was walking the dog, I noticed a car (SUV, actually) parked in front of one of the apartment houses that fill the first block of our street. It had been ticketed - a miracle in and of itself, except it had probably been there all night - and as I smirked to myself, two guys and a girl come out of the apartment.

Girl: Omigod, we got a ticket!!!

Boy #1: It says, parking in a no parking zone. When did this become a no parking zone???

(All three look at battered sign on telephone post directly opposite them. It says, "No parking either side.")

Boy #2, with great confidence: They put up old-looking signs so you can't protest the ticket.

Honest to god, that's what happened.
