Years ago, probably more than 20, my brother and I were watching the Olympics on a Canadian station. Long before getting results online, or having multiple stations showing events. That night, whoever carried it in the US was showing the same event we had seen earlier that day. We start talking about the athletes, their countries, how we think they will do, etc. Our parents start looking at us strangely and ask us how we know all this. We told them we're just really into the Olympics. Eventually we did tell them we had already seen the event earlier that day.
