Flying Cow Leaves Two Police Cars in Flames

Need I say more? It is the sort of headline where you understand all the words--"cow," check, "flames," check, "police," check, "cars," check, and "flying," another check. But then when you arrange them in that order, it doesn't make sense. The headline could just as easily read:

"Flying Police Car Leaves Two Cows in Flames"

or even

"Flying Flames Leave Police Car in Cow"

and my reaction would be just the same. Huh?
