And since death comes in threes - I'd be remiss in not mentioning the demise of Marilyn Chambers: a porn star from the era before there were porn stars (or home video).
She deserves honorable mention because she once attempted to have sex with Larry King - yes, that Larry King - on his nationally syndicated radio show. I say "attempted" because Larry couldn't get it up.
What? You were expecting a dignified tribute to Marilyn Chambers?
