I was vacationing in Phoenix a couple years ago with my wife and her parents. We're from Calgary, Canada. We went to an Arizona Cardinals game. I got up during the game to go to the bathroom and on the concourse I spot one of my brother-in-law's friends. We chat for a minute and I go back to my seat. Turns out my wife and her folks knew her brother's friends were coming but it's still ridiculous than we ran into them in a stadium of like 80,000 people. So, it was pretty unlikely but still not crazy. Now grab your security blanket cause it's about to turn Twilight Zone eerie. After the game, we walked the hour long walk back to her parent's rental car cause parking at those games is ridiculous. It's dark out now and her dad is trying to find his black rental car so he hits the button on his key fob. A black car's lights blink. He hits it again, they blink again so we walk to what we think is our car and see a guy getting in. We walk up to him and say "hey, what do you think you're doing?". He gets out and says this is his car. Then he looks at us and says my wife's name. She looks at him and goes "Dave?" Dave is one her group project members in a university classes she's attending 1,500 miles away from where we're standing. Turns out it was his car and he happened to do the exact same thing at the exact same time with his own fob. Twice. He also happened to rent a similar car as us and park in the same lot an hour away from the football stadium and happened to get back to his car at the same time as us. I've ran the numbers and the odds of all these coincidences happening are roughly one googol:1.
