No really stupid, but kind of silly.
I was grocery shopping this afternoon and I'm heading down the soda aisle and a father and his two sons are blocking the aisle. So I approach, stop and look annoyed. The younger son (probably 6-7 years old) is arguing with his older brother (probably 14-15). The father is just standing there (probably wondering how he raised his kids to have the following conversation).
It goes something like this:
Younger Brother: You're a Nazi.
Older Brother: <smiles>No, you're a Nazi.
YB: <starts to cry>No, you're a Nazi!
OB: You're the Nazi.
YB: Dad, he called me a Nazi. He's the Nazi. <still whining/sobbing>
At this point, I was able to squeeze by and get the hell away from them. The Nazi name calling continued until I was out of the aisle. Talking about bizarre.
