How did those cows grow wheels? Genetic modification? Really good grass (man)?

None of the above. They're actually our cow vans, complete with horns, eyelashes, udders and a tail. There's even a button which, when pressed, makes the cow go "Moo".

The van on the right is simply called Holy, and is a West London Longhorn. A recent addition to our herd is pictured below, and goes by the name of Pat. Pat is a Lancashire Shorthorn, and her little horns mean that she can fit into all of those car parks that have pesky height restrictions.
