Rocks for spying

I found this story quite amusing, I mean who uses a rock. Particularly a rock that doesn't even look like a rock and clearly has a gap for the secret camera and microphone to go into. Stupid lousy rock, didn't they know that the russians ate all their rocks during the glue famine of '53. Without glue the rocks were all ground up and used to feed starving KGB agents so placing a fake rock where there were no other rocks was always going to look suspicious. I always choose to hide my spy equipment in elephants. No one ever suspects the elephants.
