Okay, since other people are sharing stories now, here's a weird one.
We'd just moved into our new house a few months earlier. The doorbell rings at 10:00 at night. I glance at my wife, tell her to grab the phone and be ready to dial 911.
It's my neighbor, the weird dude who lives next door. We'd met right we moved in. Not scary or anything, but he's obviously foreign-born, speaks English but heavily accented, and just has a different way about him. It's night time and cold (first snow of the year) so I open the front door but leave the storm door closed. He yells through it "Excuse me! Do you have seventy-five dollars?"
I'm thinking "what the fuck...?" But this is my neighbor, literally lives 50 feet from me, and if he's knocking on my door 10:00 at night asking for money, maybe he's in some kind of trouble or there's some kind of emergency.
I check my wallet. As usual, pretty much nothing.
"Sorry man, no I don't."
"Well, in that case, you better move your car. It's snowing. If the plows come and you're on the street, you'll get a $75 ticket." He turns and starts walking away.
I take a second to process all this, then push the door open and yell "Thanks!" at him. He waves, and he wanders back over to his house. Interesting way to educate your neighbors, but it worked. I got my shoes and coat on and moved the car onto the driveway.
