Not Rearing Pigs

I received a cheque for three thousand pounds For not rearing fifty pigs! I laughed and I cried, I was aghast, so I danced a little jig! The difficulty is…. not knowing how You keep a detailed account? Of the pigs not reared in any one month, It could be a large amount! So I wrote and asked which pigs not to rear Was it bacon or porkers as well? Gloucesters and Saddlebacks were both rare breeds As far as I could tell! Do I get a large bonus for not rearing these? Put me down for a hundred a night. In six months or so a millionaire I’d become: I won’t put up much of a fight!
