Ezra, showing me his LEGO creation: Mommy, this is a Bat Runner. If you push this button, it will go and go and go all night and day and never stop. Will a canyon stop it?
Me: ...no?
Ezra: Not at all! What if it runs into a house, can that stop it?
Me: No?
Ezra: No. It will go right over the house and keep going. What if a shark eats it? Can that stop it?
Me: Yes?
Ezra: No! It will go in and come right back out. Can an earthquake stop it?
Me: No?
Ezra: No. It will go in the earthquake and come back out. Can it stop a tornado?
Me: Yes?
Ezra: It can stop thirteen tornadoes. Would you like to ride in this crazy vehicle?

Crash from the next room.
Me: Is everybody okay?
Ezra: Yes!
Me: Good.
Ezra: Or maybe the opposite.
