1. John Stamos and Lori Loughlin first met through their soap-opera connection. When he won an Emmy for his role on General Hospital, it was Loughlin who presented it to him.
  2. Stamos and Loughlin never dated in real life, but he's since called her "the one that got away," saying they never got together, because the timing was always off.
  1. Scott Weinger was Candace Cameron Bure's real-life prom date. (They went as friends.)
  2. Meanwhile, Andrea Barber, who played Kimmy Gibbler, brought her prom date on set, where the pair posed for pictures with the cast. The show's hair-and-makeup team helped her get ready, and producers adjusted her shooting schedule so that she could go to the prom after taping.
The Characters
  1. D.J. is the only main character who's not in every episode. She didn't appear in "Subterranean Graduation Blues."
  2. Jesse Katsopolis was born with the name Hermes. In the show, it's revealed that Hermes was Jesse's great-grandfather's name, but after being teased about it as a kid, Jesse begged his mom to change his name to Jesse in honor of Elvis Presley's late twin.
  3. Stamos was first cast to play Adam Cochran, but the character's first name changed to Jesse before the show aired. Later, Jesse's last name was switched to Katsopolis because of Stamos's Greek heritage.
  4. Dave Coulier stole the catchphrase "Cut it out!" from his childhood friend Mark Cendrowski, who now directs The Big Bang Theory. Coulier first used the line on a Nickelodeon show called Out of Control, and he later decided to work it into Full House, too.
  5. Remember when Kimmy rides a unicycle during the phone-athon episode? That came about because Andrea already knew how to unicycle thanks to a unicycling class she took one Summer with a friend.
  6. For Stephanie Tanner's dancing moments, Jodie Sweetin brought in her real-life dance teacher and friends she danced with in real life to join her for the routines.
