Back in the day when people actually picked up the phone when it rang, it was pretty common to receive calls from people who had meant to call someone else. Wrong number phonecalls forge a brief, random connection between two strangers that can be all kinds of strange. Much stranger and more intriguing than your mom calling to ask what you had for lunch, or robots trying to sell you something (the only kinds of phonecalls I ever receive).
1.) From BunkleStein15:
I got a call and did not recognize the number so I ignored it 3 or 4 times until I gave in. I picked up the phone and before i could say anything a guy with a Brooklyn accent starts talking in panic and he said "YO THAT GUY WE SAW WAS ONE OF POLISH TOM'S BOYS IF HE SHOWS UP DON'T SAY SHIT ABOUT LAST NIGHT" and said " Sorry this must be the wrong number." he just started cursing and hung up. Ever since then I have been curious who What this "Polish Tom" looks like.
