It’s a new punishment for offenders

Much like the ankle tag for other criminals, or the fluorescent jackets worn by Community Servicers, molesters now have to have a zebra grafted to their buttocks for the punishment period. Makes them easier to spot, and if one does approach a female she merely has to roar like a lion to make the zebra run away. See? Lateral thinking. Stick that in your pipe and smoke it, De Bono.
