Also fun but not entirely relevant fact: on a recent episode of Showtime's Inside Comedy, Billy Crystal related a story about how he used to open for Sammy Davis Jr. on tour and every night after Crystal had done his set, Sammy would come out and tell a long story about an event from his long friendship with Crystal. These were always surreal and completely false, they didn't know eachother previous to the tour and didn't socialise at all.
