See, Paul hasn’t gone crazy with madness.  He’s gone crazy with parental overload.  It was easy when he first thought of her as a pet and then as some smart thing.  But a fully learning, growing animal who’s cute to boot?  It’s like that joke about why babies are adorable – it’s so we don’t use them for rocket fuel.  Because rocket fuels need to be ugly to work, as is my understanding.  I am positive I am getting this joke right.
