The toll as of now includes the following: David Carradine, Ed McMahon, Farrah Fawcett, Michael Jackson, Billy Mayes, Walter Cronkite and Frank McCourt.
Now, McMahon, Cronkite and McCourt were all old as dirt in the middle of summer and as such understandable, and Fawcett had been terminally ill for quite awhile, so the only real shockers were Carradine, Mayes and Jackson (though apparently the people around MJ all had been expecting it, though not enough to take any steps toward preventing it). I'm not sure whether we're just hyper aware of the deaths because a few of them were so high profile, or whether it really is unusual, but all I'm saying is if I were Patrick Swayze I'd be keeping two eyes open and looking over my shoulder right now.
