A friend and I used to discuss an idea called, “The tank in the ER”. At the time, the show ER was doing some ridiculous things on TV and we kept expecting a “Scene from next week” to have Noah Wylie yelling, “Oh my God, THERE’S A TANK IN THE ER!!!!” ER got close a couple times, and I think we all would have been more comfortable if this sign had been posted.
