A little boy embarrasses his mother when they’re out by loudly asking if he can go for a pee. His mother tells him, "Don’t shout out like that. In future, if you want a pee, just say, 'I want a whisper,' and I’ll know what you mean." A few days later, the boy goes into his parents’ bedroom and finds his dad having a nap. "What do you want?" asks dad. "I want a whisper," says the boy. "Okay!" replies dad. "Whisper in my ear."
