Two boys around about 8 years old are playing in the street.
Where did you get the new bike from? one says to the other.
Well mum and dad seem to disappear to the bedroom the same time , every Sat afternoon. If you walk in on them they will promise you anything to get rid of you.
Great says the other boy. He finds out when his parents go upstairs, gives it 10 minutes and bursts into their room.
" What do you want his dad shouts"
"I want a watch" the boy says.
"well come in and shut the door", says his father
