Can horses blowup?

Rocco: Mom, can horses blowup?
Gabby: Rocco, horses CAN'T blowup.
Me: What do you mean... can horses blow air up into the sky? OR, do you mean blowup... like explode?
Gabby: Mom, he thinks horses can explode! Horses can't explode!
Me: Gabby stop.
Rocco: I MEAN CAN HORSES BLOWUP! EXPLODE?
Me: No! No... horses don't just blow up! You crazy little man...
Rocco: No! I mean... if they have a missle in them?
Me: Rocco?! No. Completely impossible.

And people say girls are complicated!? Little boys sure can be strange and curious (but funny!) little creatures!
