Sammi: "Guess what Daddy??? A girl in my school got crunches!"
Me: "She got what?"
Me: "What are crunches?"
Sammi (rolling her eyes): "She fell off the monkey bars at recess and broke her leg so now she needs crunches to walk."
Me: "Ohhh... You mean crutches."
Sammi (exasperated): "No! I mean crunches!"
Me: "Oh, okay - calm down. Why do they call them crunches?"
Sammi (sighing): "Because, that's the sound your bone makes when it breaks... Duh."
