Shopping with kids

A woman takes her little three year old son shopping with her. When they get to the check-out there is a very large women in front of them in a business suit yakking on her mobile. After a minute of being in the queue the little boy says "Gee, she's fat!"
The mother is horrified and admonishes the boy quietly so nobody can hear.
A couple of more minutes pass and the little boy stretches his arms as far as they'll go and says "Mummy her bum is this big!" at this the woman turns round and glares at the little boy so his mother gives him a loud dressing down about not being rude!
The little boy suitably chastised stands there in silence when the women gets an SMS on her mobile phone "Beep, beep, beep" and the little boy yells "Run for your life, she's backing up!"
