Sometime in the early 80s.
A father sends his kid to bed. Five minutes later, the boy screams, “Daaaaad! Can you get me a glass of water?”
“No. You had water when you brushed. Close your eyes and go to bed.” said Dad.
A minute later the boy screams, “Daaaaad! Can you get me a glass of water?”
Dad says, “No. You had your chance. Next time you ask, If I have to come up there, you are grounded!”
“Daaaaad! When you come up to ground me, can you bring me a glass or water?”
