Action Cow

A cow that attempts to wipe out your car and pregnant wife by lurking in its field, until the very last moment, and then leaping up over a stone wall inches from your front hood. Native to single track roads in Cornwall. Highly dangerous. Once their attack is foiled by ABS and a screaming wife, they look at you blankly -- whilst you reprimand them for a couple of minutes -- trying to act as innocently as possible.

I love cows, but these blighters make even me swing towards dairy intolerence.
