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, OK?"

OK, "the 4-year old agrees with enthusiasm."

The mother walks into the kitchen and asks the 7-year old what he wants for breakfast.

"Aw, 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 the4-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."
