A man was very sick. Doctors feared the worst. He is at home one day, resting in his bed. He looks up and says, “Is my wife here?”

His wife replies, “Yes, dear, I’m here, next to you.”

The man continues, “Are my children here?”

The man sits up and says, “Then why in the world is the light on in the kitchen?”
