Two brothers, aged 7 and 4, were in their room getting dressed before breakfast.
"I say it's time we started swearing like Dad" said the 7 year old. "So, when we go down to breakfast, I'll use the word 'damn' and you use the word 'ass'."
"OK" said the 4 year old.
When the boys get to the kitchen they hop up on to their chairs at the table.
"What do you want for breakfast, boys?" asked their Mother.
"Let me have some damn Cheerios" said the 7 year old.
One second later the Mother took her wooden spoon and laid it across his behind with a loud "Crack!" Screaming at the top of his lungs the 7 year old ran upstairs.
"And what will YOU have for breakfast?" said the Mother turning to the 4 year old.
"Well, I'm not sure", he said, "But you can bet your ass it isn't going to be Cheerios."
