John Byner (né Biener; born June 28, 1938) is an American actor, comedian and impressionist who has had a lengthy television and film career.

His ability to mimic "Toastmaster General" George Jessel came in handy during his appearances on panel programs such as celebrity roasts and other tributes.

He then hosted his own show in 1972 called the John Byner Comedy Hour, where the character Super Dave Osborne, portrayed by Bob Einstein, was first introduced.

[5] In the 1970s, Byner appeared several times on The Carol Burnett Show, where in one comedy sketch he wore a Donald Duck costume and mimicked the cartoon character's distinctive voice.

[6] In the 1980s, he hosted Bizarre (produced and filmed in Canada), which re-introduced many people to hapless daredevil Super Dave Osborne played by Bob Einstein.

He was a regular celebrity guest on Hollywood Squares during the John Davidson years and later hosted the 1988-1989 syndicated game show Relatively Speaking.

On the February 13th, 1997 episode of Judge Judy, Byner appeared as a plaintiff against the agent Dan Jordon and won a judgement of $3,500 as a kill fee for the cancellation of a stand up comedy performance.
