take your breath away

Will: (Out of the blue, and very matter of factly) "It's so hot in
Texas that it pulls out your breath."
Erin: "What? Oh, do you mean it's so hot in Texas that it takes your
breath away?"
Will: "Yep!" (30 seconds later...) "When do you get it back?"
Erin: "Get what back?"
Will: "Your breath!"
Erin: (While trying to stifle laughter) "What do you think?"
Will: "I think we get it back when we go to Grandma and Grandpa's
where it's cold. We get our breath back when it gets cold."

This follows from the fun recent discovery of Will's that he can see his breath when it's cold.
