This is so funny and you’re spot on. The first day I met my girlfriend she came from the Giants’ Super Bowl Parade in 2008. I still wasn’t sure if she was really a Giants fan or just along for the fun of a parade. Eventually we started dating and her fanhood seemed legit. One Sunday we were watching a game and were making out on the couch, passively watching the game for a moment. So the volume is up but eyes aren’t on the screen. In the background we hear the referee’s mic pop on and he says, “holding, number 67.” My girlfriend stops everything and yells, “Fucking McKenzie!” I was blown away. Not only did she know the lineman’s name but she knew the number. I was absolutely convinced and that girlfriend is now my wife. It’s a foolproof test.
