#2673 came around from his inter-planetary realignment with a start. He was in a dark, smelly room, full of strange noises. His mission from The Elders of the planet Sysyphus 12 repeated in his head...

Standing, he retrieved his probing equipment from his metal carry-case. He switched to night vision, focusing on the four-legged, black and white creatures in the corner.
Ah, the humans!
He approached the nearest cow and planted his probe into its anus. The Elders will be so proud #2673 thought.
The cow looked angry.
