"You look after these sheep while I go and pick up the mother-in-law. Tell ya' what, you count these sheep while I'm gone and tell me how many there are when I get back."
The sheep-dog complies and the shepherd sets off. When he gets back, he asks his dog,
"Alright how many were there, then?", to which the sheep-dog replied,
"There's a 140 of 'em." The shepherd then said,
"What? That can't be right, cause when I went to the market this morning to get 'em the seller told me there was 138 of 'em!"
The sheep-dog then said, " Yeah, there are, but I rounded 'em up for you!"
