9. The stock market takes a crazy hit.

This day is now known as “Black Friday” to people familiar with the events of Friday, October 13, 1989.  On that Friday a crash occurred which was apparently caused by a reaction to a story of the breakdown of a $6.75 billion projected buyout deal for the parent company of United Airlines.

13. Bob Renphrey had the absolute right idea.

After numerous problematic occurrences on various Friday the 13ths, Bob Renphrey had had enough. He’d sustained injuries from a glass door, his wife had fallen down a flight of stairs, he crashed a motorcycle, and he fell into a river. So the North Wales native decided to say fuck it, and spend the remaining Fridays that would fall on the 13th in bed. After he died in 1998 his funeral was scheduled on (you guessed it) Friday the 13th.
