A father and he's 6 year old son walk into a bank. When they get in line the son notices the very large woman in front of them. The son tugs at the dad's jacket and says, ""Daddy, look! That lady is huge!"" the father replies ""yes son she's as big as a truck"". About a minute later the large woman's beeper goes off and the kid pushes his father out of the way and yells, ""Look out dad!!! It's backing up!""
