Oldie but a goodie

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 started swearing."

The 4 year old nods his head in approval.

The 7 year old says "When we go downstairs for breakfast I'm going to swear first, then you swear after me, 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.

"Oh shit mum, I suppose 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 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 it won't be fucking Coco Pops."
