Gamma Exposed

Today, when we were driving home from Sam's along Sooner Road, we drove by a McDonald's that is built into a gas station just south of I-240. Andrew said "McDonald's."

Evan: "Does grandma take you to McDonald's?"
Andrew: "Not that McDonald's."
Evan: "Does grandma take you to a different McDonald's?"
Andrew: "Yeah."
Evan: "Which grandma: big grandma or little grandma?"
Andrew: "Big gamma."

Well ... there you have it!
