As a godfather, I've laid "mines" in the homes of my adopted family on several occasions. Granted, the "mines" that I set were patches of bubblewrap on the floor just inside the entry doorways to alert myself as well as the father of the girls that were arriving late, so that we could have "a chat" with the boys bringing them home late. Unfortunately, the boys seemed to have been conditioned as sprinters because the moment things began making the popping sound they took off like a race horse. Perhaps I over did it when I made photo copies of their ID's before they left for the date? *shrugs* A good godfather's job needs to be done thoroughly.
