[Scene: I overhear Luke, age 8, in the next room talking with his sister Beth, age 4]
Luke: "Everybody on Earth is crazy."
Beth: "Me and you are not crazy."
Luke: "Yes we are. Everybody is."
Beth: "Are snakes crazy?"
Luke: "Are snakes people? No. Only people are crazy."
Beth: "What about rabbits or chickens?"
Luke: "Maybe a little."
Beth: "Well, I'm not crazy."
Luke: "Yes you are. So am I. And especially Dad."
Beth: "Oh yeah, he's really crazy."
"I don’t think I can stop talking. Even when the rest of me is tired, my mouth never gets tired."

— Luke, age 8, in response to being asked to please stop the incessant talking for a few minutes because we were all tired from a crazy day

"You know what really scatters my mind? To think that we almost aren’t really here. We’re just tiny specks walking around on a little blue speck flying through the universe! I mean, that’s just crazy!"

— Luke, age 8

"See those shoes? I can tell they belong to a girl. I know girls. They’re all crazy. Only crazy people wear shoes like that!"

— Luke, age 8

Indian name
Grandma: "Do you know my Indian name?"
Luke: [age 8] "No."
Grandma: "It is 'Miniwapichi'. Do you know what it means?"
Luke: "Probably 'Crazy Grandma'."
Grandma: "You little rascal. It means 'Dancing Waters' in Lakota."
Luke: "I bet it really means 'Crazy Grandma' but they didn't want to tell you that."
Nonsense
Luke: [age 7, improvising a song] "You know what I like, like like? I like poisonous electrocution with afros!"
Me: "Come on, now, that's just total nonsense coming out of your mouth."
Luke: "Total nonsense? That's the point of a boy! All my words are To Stupidity and Beyond!"
