Props to Couric's stunt double, Heidi, who threw a terrifying "I just died" spasm in at the end of her fall.

Holy crap, Katie Couric. I know showbiz is a brutal industry, but James Corden has only been hosting The Late Late Show since last Monday. Do you know how often he probably thinks "gee, as long as no one actually dies on my show, at least I'll have had a better run than The Chevy Chase Show or McEnroe"? Probably a lot, because performers are very insecure people. You could die on Conan and TBS would keep its investment. But for April Fool's, you made James Corden briefly think that his entire life would be remembered simply for hosting Katie Couric's death. Bravo, you cruel, cruel newscaster.
