Your post reminded me of a funny -- but 100% true -- story that my brother-in-law told me. When he worked for the old Cellular One, he used to do corporate training, and they still had those old big, square, M*A*S*H*-looking phones that they affectionately used to call "The Brick." Those things were actually made out of the same material that they make FOOTBALL HELMETS out of, and as part of the training, which was outside, my brother-in-law would take the phone, BANG IT really hard on the table, and then TOSS IT INTO A NEARBY POND in about 6"-one foot of water. He'd then casually walk over, take the phone out, and make a call with it to somebody's phone.
Ahh, those ol' analog bricks would give ya tumors, but you couldn't beat 'em for CLARITY, kwim??
