What is the most ridiculous coincidence that has ever happened to you?

Here, I'll give a few to start:

So during the summer I was having a kind of hard time getting over my ex. I was quite proud of myself when I got to a party, saw him with another girl, and realized that I didn't care. I had finally gotten over him. Later during the party I met this guy and the party was kind of lame so the guy asked me if I wanted to come back to his house for a few drinks and to hang out. Since his place was on the way back to mine anyway (he told me the road it was on) I just said sure. Upon getting to the road and walking to his door I realized that he was the random guy that was living upstairs in my ex's house. This guy had no idea we dated. I also got to hear my ex bring home the girl from the party as they loudly did things downstairs.

Another has to do with this guy that was trying to get with me all summer. He was in a different city during the summer (we went to the same college) but insisted on texting me every day without actually knowing me. After dealing with that, during the year I met this other guy at a tournament for a club I'm in (he went to a very different college not in the same city). After screaming in my ear (and other shenanigans) he asked me for my number. He then proceeded to text me non-stop in a way that reminded me of the guy from the summer. When he added me to Facebook I noticed that he went to high school (a random high school that was more than a state away mind you) with the summer guy and he was our only mutual friend on Facebook.
