Sally phoned her husband, Bill, at work for a chat. “I’m sorry dear,” said Bill, “but I’m up to my neck in work today. I don’t have time to chat.”
Sally replied, “But I’ve got some good news and some bad news for you, dear.”
“OK darling,” said Bill, “but as I’ve got no time right now, just give me the good news.”
“Okay,” agreed Sally. “Well, the air bag works!”
