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