Late one night a friend and I are trying to coax his cat Merlin back inside from across the street.
After a good bit of coaxing, my friend says "c'mere Merlin" in a high pitched voice. (You know, the voice we use when we talk to small cats.)
Across the street we hear "c'mere Merlin" coaxed back at us in a different voice. Nobody, to the best of our knowledge, was over there. We ran back inside and freaked out.
