Swearing

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, so the 7 year old says, 'When  we  go downstairs for breakfast I'm gonna 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 don't know, 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 f*****g Coco Pops'
