Reasoning John Cleese could be proud of

Here is the rough transcript of a conversation I just had with Andrew:

"Andrew, did you just hit your sister with your axe?" (Plastic, but still . . .)

"Yes."

Upon said confession, axe was duly confiscated and I tried to talk to my teary-eyed boy.

"Why did you hit her?"

"I was just chopping wood."

"Is Evelyn made out of wood?"

"I didn't realize she wasn't made out of wood. It was an accident."

(A witch? Anyone?)
