An older couple are in bed one night, and the woman wakes up and says,
"Sam, get up and close the window. It's cold outside." The fellow just
keeps right on snoring. A little while later, she nudges him and says
again, "Sam, get up and close the window! It's cold outside." He's about to
go back to sleep, but she keeps shaking him, and so finally he gets up and
shuts the window. He gets back into bed and says, "So now it's warm
outside?"
