A seven year old and a four year old are upstairs in their bedroom.

"You know what?" says the seven year old, "I think it's about time we
started swearing."

The four year old nods his head in approval.

"When we go downstairs for breakfast I'm going to swear first, then you
swear after me, ok?"

"Ok" the four year old agrees with enthusiasm.

The mother walks into the kitchen and asks the seven year old what he wants
for breakfast. "Oh, shit mum, I think I'll have some Coco Pops."

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 four year old and asked with a stern voice, "And what do
YOU want for breakfast, young man?"

"I don't know," he blubbers," but it won't be f***ing Coco Pops."
