Over a decade ago my dad and uncle decided to watch a new episode of Family Guy together, but from their own homes and talking to each other through the phone. They accidentally found out that my uncle's TV was slightly behind my dad's even though they were watching the same show, on the same channel, at (almost) the same time.

I don't understand why they decided to do that that night. They haven't done that before or since. I just thought that it was kind of funny that they discovered such a thing by accident.
