For those unfamiliar with ER, it was a long-running medical drama known for its gritty realism, depth. Then you had Dr. Robert Romano, the show's resident jerk: a brilliant surgeon but a complete ass. During an earlier season he had his arm chopped off by a helicopter. It just whomp, sheared it clean off while he was on the hospital helipad. But then a season later, Romano was later killed by another helicopter. This one straight-up fell off the roof and crushed him while he just screamed, "NOOOO!" before he got pancaked.
