Its time we started swearing..?!

A 7yr & 4yr old are in their bedroom, 'You know what "says 7yr old, "I think it’s time we started swearing. When we go downstairs for breakfast I'll swear first then you". "OK" says 4yr old. Mum asks 7yr old what he wants for breakfast. "I'll have Coco pops, bitch". WHACK, he flew out of his chair crying his eyes out. Mum looked at 4yr old & said sternly "and what do you want?”.”Dunno, but it won't be fucking coco pops.”
