Not only was an overdose of propofol likely to blame for Joan Rivers's death, her doctors didn't have the proper equipment to deal with just that type of emergency.

Legendary comedian and talk show host Joan Rivers has left the world with a little less laughter today -- the feisty television mainstay known for her hilarious candor and dizzyingly quick wit has sadly passed away at the age of 81, following complications during a surgical procedure.

David Letterman gave Joan Rivers a taste of her own medicine last night (Tuesday), walking out in the middle of an interview. But don't worry -- it was all in good fun.
