A little lad came home from his fishing trip.

He says to his Mum, "Look, Mum, I've got some dam fish!"

His mother says, "Don't you talk like that please! That's not very nice!"

The little boy says, "But Mum, I call them the dam fish because I caught them when I was fishing near the dam!"

"In that case," she says, "I'll cook them and we'll have them for tea."

So at teatime the family are all sitting around the table and Dad says to the lad, "Please pass the dam fish, m'boy."

The lad says, "Sure, here you are, Dad. Now please pass me the fucking potatoes..."
