A 7 year old and a 4 year old are upstairs in their bedroom. You know what?" says the 7 year old, "I think it's about time we start swearing." The 4 year old nods his head in approval. "When we go downstairs for breakfast I'm gonna say 'hell' and you say 'ass',o.k.?" "O.K." the 4 year old agrees with enthusiasm.
The mother walks into the kitchen and asks the 7 year old what he wants for breakfast.
"Awe, hell mom, I guess I'll have some Cheerios."
WHACK!! He flew out of his chair, tumbled across the kitchen floor, got up and ran upstairs crying his eyes out.
She looked at the 4 year old and asked with a stern voice, "And what do YOU want for breakfast, young man?"
"I don't know," he blubbers, "but you can bet your ass it won't be Cheerios!"
