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, said the father.

A minute later the boy screamed,
Dad!! Can you get me a glass of water?

No. You had your chance.
The next time you ask, Im going to come up there and give you a good spanking! said the Dad.

Two minutes later the boy screamed,
Dad! When you come up to spank me
can you bring me a glass or water?
