One night a father sent his kid to bed. Five minutes later the boy screamed, “Dad! Can you get me a glass of water!?!”
“No. You had your chance.”
A minute later the boy screamed, “Dad!! Can you get me a glass of water?”
“No. You had your chance. Next time you ask I’ll come up there and spank you.”
“Dad! When you come up to spank me can you bring me a glass of water?”
