My , now deceased brother-in-law, was a missle expert for the US, and quite a jokester. He knew all his personnel had to have their phones on 24 hrs. One Sunday morning he called one of his buds and in the perfect gay voice, and scolded him about leaving his toothbrush on the counter. Come to find out, the bud was at church sitting in the middle of the congregation when the phone went off. Nevertheless, the next day of work, bro in law came out in the afternoon to go home (they are locked in a bunker all day) to find his Cobra replica filled with foam packing beads. He never did it again.
