The Simpsons Did It
This was long ago in the days before smartphones. Probably the 4th grade or so. It all started when my buddy and I were arguing about an episode of The Simpsons. It was the one featuring the Mattel and Mars Bar Quick Energy Chocobot Hour.
I was arguing that Col. Kataffy was one of the chocobots. Eventually I realized I was wrong, but refused to admit it. This debate went on for weeks. I even went so far as to make up things in the episode that proved my (false) point.
He started out totally sure of himself, but by the end I am pretty sure he was doubting his sanity. Eventually he let out one of those nerd-rage half shriek half grunts and tackled me to the ground. At that point I couldn’t help but burst out laughing and admit I was just messing with him. Story credit: Reddit / AllMightyTallest
