Let's write a story.

Them the cows met some aliens that sent them back to earth

but the aliens put a chip in thier lungs

So they can come back to earth when it's time to invade

It forces people to sound like a car alarm every time they yawn

The cows however, started plotting their revenge, and slowly took over the multi-giga-omni-whatev-verse and finally set their sight upon bob

So they got their gloves on some nuclear weaponry

and prepared to click clear alerts- *ahem* launch nuclear bomb

...

Then the world plunged into WW3

Then he died the end
