What are colives, and should you eat them?

The bar for wacky cow ads has been raised foolishly high of late. From Wieden + Kennedy's purified Cravendale cow (certified not racist!) to Draftfcb's talking-teat Oreo temptation, we've feasted on some bloody breakthroughs in bovine. Enter Campbell Mithun's "Colive" commercial above, touting Land O'Lakes Butter with Olive Oil. The setup, showing what happens when you cross a cow with an olive, would seem to present possibilities. A giant green heifer spurting pimento-flavored milk sprang to mind.
