A little boy and his dad are standing in line at the grocery store behind 
a big fat lady. The little boy says, "hey dad, look how fat that lady is!"
"Shhhh, quiet son, she'll hear you."
"But dad, look how big and fat that lady is!"
"Shhhhhh, don't say that son, it's not nice!"
"But dad, look how big and fat that lady is!"
"Shhhhhhhhhhhhhh, don't say that son, it's not nice and it's rude!"
Suddenly the fat lady's beeper goes off.
"Look out dad, she's backing up!"
