Young Tom and Harry are up late one night and they're watching late night TV while their Mum is in bed. They're really impressed (as kids are) with all the swearing and think it's the coolest thing ever.
So next morning, they're sat down at the breakfast table and their Mum asks them want for breakfast. Suddenly Tom pipes up "S**t Mum, I want cornflakes this morning!" His Mum is absolutely horrified by this and smacks him so hard it sends him flying accross the room. He gets up and runs off, sobbing. Harry sits there, stunned.
Mum then asks Harry "So, what would YOU like fro breakfast young man?". Harry looks up and says "I don't know, but it won't be f**king cornflakes!"
Can't remember where I read that but it cracks me up.
