Brother or Sister

The other day I had a conversation with Henry in the car and this is how it went:

H: Mom, why don't we adopt a brother or sister for me?
M: I wanted to but your father didn't.
H: Well let's just do it and surprise him.
M: You can't do that - it's against the law - daddy would have to know about it.
H: Well it's probably a good thing I don't have one anyway.
M: Why?
H: Because I would just torture them.
M: (Sigh)!
