The funny thing is, that as weird as that old cliche sounds, it is amazing just how many times it is proven true. Even in my own family, whenever there is a death of a relative, more often than not, within the next month or two we get word of two more deaths as well.
As for Saddam, I don't think he counts. The first two are famous people, Saddam is more infamous. And as previously mentioned, Joseph Barberra is close enough to fill that third (or should we say first) slot.
