A 5 year old and a 4 year old are upstairs in their bedroom.

"You know
what?," says the 5 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 5 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 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."
