An executive is at work in an office. Something urgent crops up, and he realises that he will have to work late. Being a considerate sort, he telephones home to let his wife know that he will be late. A little boy answers the telephone, "Yeth ?"

"Hello, son. Where's your mommy ?"

"She'th upthtairs in the bedroom with Uncle Fred."

The man thinks to himself, "The bitch!". Then he recovers and says, "OK son, I want you to do me a favour. I want you to go to the foot of the stairs and shout, 'Daddy's home', as loud as you can. Then come back to the phone and tell me what happened."

There is a clunk on the line as the receiver is put down, and some vague noises off. Then the little boy picks up the receiver again. "I did what you thaid, and Mummy thtarted thcreaming, and Uncle Fred jumped out of the bedroom window without any clothes on, and landed in the thwimming pool."

"Well done, son. Hang on ! Swimming pool ? I haven't got a swimming pool ! Is that Hadfield 43278 ... ?"
