My friend was once an avid-prank caller which used special programs to get away with sending police to a house. One day he called up some store with a public camera outside in Bosnia and told them that they had Serbian girls (so the police won't give a fuck). The owner said "If you bring 'em in 30 minutes, we'll take care of them" in a way that was so nonchalant it was as if he was actually interested in it. After a moment of silence, my friend hanged up and swatted the store, while we were able to watch on the street camera.
