[Spoiler alert if you still haven't seen Sunday's Good Wife.] "What the hell happened?" is the first thing David Letterman said to Josh Charles as the actor sat down for his Late Show debut last night. Letterman, of course, was referring to the actor's surprise death on Sunday's Good Wife. Charles talks about the decision to leave and how personally people have reacted, with one neighbor writing him a note saying, "We feel like a family member had died." Charles, however, didn't read the rest of the note, which said, "Because one did. We are sitting shivah. Please stop talking about your fake TV death so loudly."
