Dancing Cows - Dairylea Cheese

In this commercial, a chorus of musically talented cows — and one bull — perform a catchy song and a (sort of) dance, while preaching the benefits of Dairylea cheese. As it turns out, it's all about the cow's diet: "when you try Dairylea there's no better to be found, because Dairylea cows eat grass all year round." The cows are not computer animated — rather, real footage of cows is creatively edited and reversed to fake their musical performance. The dancing cows advertisement originally screened in a longer version in the United Kingdom, before hitting Kiwi television screens in the early 1990s. 

The reason's right here in grass you see, it's what makes Dairylea the way cheese should be.
