Moondoggie is a fictional character created by Frederick Kohner in his novel "Gidget, The Little Girl with Big Ideas".
 He appears as a principal character in five of the eight Gidget novels, but is a minor character or is only mentioned in passing in "Cher Papa", "The Affairs of Gidget" and "Gidget Goes Parisienne".
 He is portrayed as a surfer who saves Gidget from drowning and later becomes romantically involved with her.
 In the novels, two of the television movies and "The New Gidget", his real name is Geoffrey H. Griffin (the middle initial is mentioned only in the first novel), but in the three "Gidget" motion pictures and the 1960s sitcom "Gidget" his name is changed to Jeffrey Matthews, and in "Gidget Gets Married" his name is Jeff Stevens.
 In the novelization "Gidget Goes Hawaiian" we learn that his nickname refers to his fondness for surfing by moonlight.
Brian Helicopter is the stage name of Gareth Holder (born 27 June 1958, Leamington Spa), an English musician, based in the United States.
 He is best known for playing bass guitar for the UK punk rock band The Shapes.

 A prolific session player, he appears both credited and uncreditied on many releases throughout the 1980s and early 1990s under both his real and stage name.
 He was one of the first bassists in the nascent UK punk scene to adopt the Rickenbacker bass guitar which he still uses to this day.
 He was also one of the first bass guitarists in the world to use Trace Elliot amplification.
 His bass playing style is characterized by a very fast precise pick attack, and fast runs.
 Unusually for a bass guitarist, he sometimes utilizes an overhand tapping technique more common to six string players.
 He continues to play professionally, reverting between his real name and his stage name as the fancy takes him.
 He is also a professional skydiving coach and instructor, currently holding seven world records in the sport.
 He can be seen in an episode of MythBusters aired on the Discovery Channel taking presenter Kari Byron skydiving whilst testing the falling airplane blue ice myth.
 He is also a vegetarian.

Brad Darrach (real name Henry Bradford Darrach Jr.; 1921–1997) was a journalist and film critic.
 A 1942 graduate of the University of Pennsylvania, he joined Time Inc. in 1945 after working for the Baltimore Sun and the Providence Journal.
 He wrote for Time Inc. magazines including "Time", "Life", "People" and "Sports Illustrated".
 During a career which spanned the 1940s to the 1990s, he profiled such notables as Elizabeth Taylor, Marlon Brando, Frank Sinatra, Fred Astaire, Barbra Streisand, Robin Williams, Bill Cosby, Jack Nicholson and Miss Piggy.
 His 1955 "Time" cover story on Marilyn Monroe, based on a chaste 10-hour interview in her hotel bed while she was filming "Bus Stop", was the first to report on the star’s traumatic childhood; in 1984, he wrote: "Out it came for the first time, the whole hideous mess: the foster homes, the religious sadists who threatened her with hellfire, the child molester who raped her when she was 6.
 Simply to remember was agony for Marilyn.
 Sometimes she was racked with sobs; sometimes she choked on anger and disgust.
 Sometimes tears filled my eyes too."
 For a 1995 Life Magazine photoshoot with Michelle Pfeiffer, he held the Hope Diamond in his hand.
