Frosties and Kids swearing

A 7 year old and a 4 year old are in their bedroom. "You know what, I think it's time we started swearing" said the 7 year old.

"When we go downstairs for breakfast, I'll swear first, then you."

"Sure." replied the 4 year old.

They make their way downstairs and their mum asks the 7 year old what he wants for breakfast.

"I'll have frosties, bitch"

WHACK, he flew out of his chair crying his eyes out.

Mum looks at the 4 year old and says sternly "And what do you want?"

"I don't know, but it won't be fucking frosties"
