All work and no play makes Jack a dull boy, so what happens when you give a pig a toy for it to play with while it is being fattened for the slaughterhouse. I suppose those green piggies from the Angry Birds franchise would be able to appreciate such a plaything, as they would then leave the birds' eggs well alone. As a result, they would be slaughtered and green slices of bacon (theoretically, anyways) would be served up, being tasty to the last bite.
