This happened awhile ago at work: I got into an argument with the cook (who obviously isn't too bright).
COOK: Do you eat fish?
ME: no. Fish is a meat.
COOK: No, fish is poultry.
ME: What the hell? Poultry includes birds such as chickens, turkeys, ducks, geese, etc. A fish is an aquatic animal, not a bird.
COOK: No, they're poultry.
ME: I raise chickens and turkeys an know for a fact they are poultry. Go read a textbook!
COOK: Do you eat pepperoni?
ME: (sigh) no because it's made of meat.
COOK: No there is such thing as a pepperoni plant. That's what pepperonis are made out of.
ME: You're kidding.
There is no such thing as a pepperoni plant. Pepperoni is made from animal parts and spices--not a plant.
he still didn't believe me so I had to get my boss to explain the whole thing to him. I mean, he's a cook and he didn't know anything about the subject of food. Doesn't surprise me, I still don't think he graduated high school yet.
