Responding to a ruling by the European Union, Great Britain enacted a law requiring farmers to provide pigs "environmental enrichment" in the form of "manipulable material"—namely a toy ball—in each pigsty, or face up to three months in jail. Otherwise, bored pigs tend to chew on each other. Farmers are told they may also need to change the balls often so the pigs don't experience further boredom.

[Ed.: I get bored just thinking about how this was decided.]
