George Clooney’s Failed 'ER’ Cast Reunion Is The Funniest Flop Ever.

For E.R. fans, watching the show every week wasn't just an hour of television -- it was a highly anticipated ritual, meant to thrust the viewer into the world of illness and medical emergencies from the comfort of their own couch. It was the longest-running medical drama in television history, and when it comes to the landscape of American entertainment, it was an institution.

That's why when George Clooney showed up to do Jimmy Kimmel Live, the host had to figure out a way to bring Clooney back into the operating room. This ode to the greatest hospital show of all time is totally hilarious -- and even includes a surprise guest who probably should have been at County General Hospital all along.
