Chain Saw

Azael (on the way into Target): "Mom, I need you to buy me a chain saw."
Mom (trying not to laugh): "Why's that?"
Azael: "I'm going to cut a secret entrance into our room so Silas and Lorelai can't get in there."
Mom: "That's a great idea. But chain saws are illegal for people under age 18."

At least he's resourceful.
