In college, I was at a party. A guy said, "You're from a dairy farm? I went cow tipping once."
I laughed, thinking he was joking. I said, "Cow tipping is fake. It's just a joke ... like country kids would take city kids out to a field to go 'cow tipping' and then leave them there." (I never did this to anyone, nor did anyone I know. It's just one of those rural myths. Both the tipping and the joking.)
"No, I did it!" he said. "We just walked up to it and pushed it over."
"Really," I replied. "They don't sleep standing up. A cow wouldn't stand still if you pushed on it. And they weigh 1000 pounds. How could you possibly push one over?"
"I just did," he said.
I just laughed and walked away. The truth wasn't going to sway him. Perhaps that's the same night he also went pegasus riding and unicorn hunting.
