Also, that one guy from the show you never saw- Karl Malden!
I don't believe that celebrity deaths come in threes- it's a psychological phenomenon known as 'passive avoidance,' or 'passive targeting.'
Basically, our minds work to eliminate outliers- so if you believe there are three celebrity deaths at a time, you'll focus on Farah and Ed and the King of Pop. You'll passively forget about Malden or Storms, because they don't fit the program of 'threes.'
