Just a random turn-of-the-century pigeon shooting
"Who's that?" she asks.
"That's what my great-great-grandfather would have looked like. He shot live pigeons. For sport."
"Okaaay."
"I found an article in a Pittsburgh newpaper from the turn of the century. He shot pigeons and apparently got into a few fights whenever he didn't like the outcome."
"So that's your great-great-grandfather?"
"No. It's just a picture of a random pigeon-shooter in the early 1900s."
"Why do you have a random picture of a guy shooting pigeons in the 1900s?"
"Have you learned nothing about your mother?"
