This is why some kids think their parents are idiots-

This morning, I was getting ready for work, and Hal was playing in the front room.

As I walked by the door, I saw him moving his hand around, making the sound of a train whistle-

Hal- "Whoo-whooooo!"

Me- "Oh, is that a train?"

Hal- "No, it's my hand."

Oh. Right.
