This reminds me of a joke told by my primary school teacher.
A little boy's mum had been quite annoyed that whenever he wanna pee, he shouts shee shee. So the mum tried to educate the little boy with grace by telling him that in future if he wanna pee, just whisper that he likes to sing.
So one day, the little boy woke his mum up in the middle of the night. The mum asked the boy what he wants and the boy mentioned that he wanna sing. Then the groggy mum told the little boy to sing softly at her ears.
