Content:  Fred Flintstone physically resembles both the first voice actor who played him, Alan Reed, and Jackie Gleason, whose series, The Honeymooners, inspired The Flintstones. The voice of Barney Rubble was provided by voice actor Mel Blanc, except for five episodes during the second season (the first, second, fifth, sixth, and ninth); Hanna-Barbera regular Daws Butler filled in and provided the voice of Barney while Blanc was incapacitated by a near-fatal car accident. Blanc was able to return to the series much sooner than expected, by virtue of a temporary recording studio for the entire cast set up at Blanc's bedside. Blanc's portrayal of Barney changed

After his recovery from the accident, Blanc used a deeper voice, quite similar to the voice of the Abominable Snowman he performed in other cartoons, and was shown as somewhat dopier than before. Reed based Fred's voice upon Gleason's Honeymooners interpretation of Ralph Kramden, while Blanc, after a season of using a nasal, high-pitched voice for Barney, eventually adopted a style of voice similar to that used by Art Carney in his portrayal of Ed Norton. The first time the Art Carney-like voice was

Henry Corden occasionally voiced Fred on records throughout the 1960s, and also provided the singing voice for Fred in The Man Called Flintstone. Following Reed's death, Corden officially took over the role until his retirement in 2000, although he continued to voice him in Post Pebbles commercials until his death in 2005. Corden voiced Fred's father and mother in The Flintstone Kids.

It debuted on November 3, 2001 on Cartoon Network and was directed by Chris Savino and David Smith.

Another character given that same vocal delivery was Chief Wiggins on the series Dynomutt, Dog Wonder, Sheriff Bagley on Clue Club, and countless others. Another voice Stephenson was often called to do was the high nasal Joe Flynn-inspired voice. This voice was usually given to characters that were either rude, or smart-alecks, or flat out mean. They were also short-tempered; examples include Mr. Peevly from Help! It's the Hair Bear Bunch!,
