Make your children recognise your voice .........
Dad: Hi honey, this is Daddy. Is mommy near the phone?
Child: No daddy, she's upstairs in the room with Uncle Paul.
After a brief pause ....
Dad: But honey, you haven't got an Uncle Paul.
Child: Oh yes, I do. And he's upstairs in the room with mommy right now.
Another brief pause ....
Dad: Uh! Okay then, this is what I want you to do. Put the phone down on the table, run upstairs and knock on the bedroom door and shout to mommy that daddy's car just pulled into the driveway.
Child: Okay daddy, just a minute.
A few minutes later the little girl came back to the phone.
Child: I did it, daddy.
Dad: And what happened honey?
Child: Well, mommy got all scared, jumped out of bed with no clothes on and ran around screaming. Then she tripped over the rug, hit her head on the dresser and now she isn't moving at all.
Dad: Oh my god .. .what about your Uncle Paul?
Child: He jumped out of bed with no clothes on too. He was all scared and jumped out of the back window and into the swimming pool. But I guessed he didin't know that you have let out all the water last week to clean it. He hit the bottom of the pool and I think he's dead.
Long pause ... longer pause ... even longer pause ...
Dad: Swimming pool? Is this 03 - 8888 8888?
Child: No, this is 8888 8880.
Dad: Oops ... sorry, wrong number.
