Hey, It's That Guy!: Like their counterparts on The Love Boat, the casting directors were notorious for scraping up every 1970s B-list and C-list celebrity they could get their hands on. Many made multiple appearances, almost always as a different customer each time. Some of the more notable guests included Carol Lynley (number one with a bullet, appearing 10 times on the show), Mary Anne Mobley (8 appearances), Barbi Benton (8), Ken Berry (7), Maureen "Marsha Brady" McCormick (6), Bob Denver (4), Carolyn Jones (4), Juliet Mills (4), Eve "Jan Brady" Plumb (3), and Charo (3). Check out the IMDB cast page for the show to see all the repeat offenders.
Michelle Phillips returned as the same character three times (Naya) and Wendy Schaal appeared twice as different characters before joining the cast as Roarke's Goddaughter.
I Am Not Spock: It's widely speculated that Hervé Villechaize was Driven to Suicide because of his inescapable recognition as Tattoo.
