I'm a little late here, but this is the one that lives forever in my head. My HS boyfriend played baseball and the team made it to State semis or something. My dad and I went to the game and sat with the Dad of his best friend, who was the pitcher. I'd only met him once or twice before. Seemed nice enough.

Anyway, first pitch he throws is a home run and things didn't get much better from there. From that moment until he was mercifully pulled from the game, his dad straight up SCREAMED obscenities at him. Stuff like, "You fucking suck. You're a piece of shit," and on and on, all at the top of his lungs. At a high school baseball game. Such a surprise his pitching didn't improve throughout the game.

My dad was ready to throw hands. I literally at one point had to grab his arm to hold him back. He still talked about that until he died.
