Someone who lies awake at night if there really is a dog.
A paint Bernard!
Out, damned spot! Out, I say!"*
A turtle. I was lying about the wheels
Lie in bed wondering "Is there really a dog?"
Someone knocking at your door for no apparent reason.
Carrion my wayward son
I didn't make an enzyme last night.
Lay awake, contemplating the existence of Dog.
Somebody who stays up all night torturing himself mentally over the question whether or not theres a dog.
Someone who lays awake at night, wondering if there is a dog.
