Unusual sighting- etiquette of it?

[MTSUGURL]

"Oh, I have friends in that sorority. Who do you know that's an ABC?"
"My daughter. She gave me this hat for Father's Day."
"Oh how sweet."

or

"Excuse me, Grandpa. Get those letters off your head NOW. I KNOW you're not in a sorority!" (Followed by large scuffle in which said hat is ripped to shreds, Grandpa gets stitches in the scratches down his face and you get arrested for assaulting the husband of your local chapter's advisor. He deserved it, the perp.)

The second would be amazing to watch.. in a I can't look away from the train wreck kind of way.
