Jennifer Garner appeared on The Tonight Show to explain to Jimmy Fallon the ludicrous bodysuit and corset she had to wear for the Oscars. Apparently, having a waist for the red carpet can involve quite a bit of work behind-the-scenes. So much so, that both Garner's internal and external organs were affected. 

The Oscars are very glamorous, right up until your ribs and bladder (sensibly) do not cooperate with a metal corset.
