Conway is perhaps best known as a regular cast member (1975–1978) on the TV comedy The Carol Burnett Show where he portrayed his recurrent iconic characters Mister Tudball and the Oldest Man.

He then gained recognition for his role as the inept Ensign Parker in the World War II TV situation comedy McHale's Navy from 1962 to 1966.

Conway starred on The Carol Burnett Show, where he was admired for his ability to depart from scripts with humorous ad libs and gestures, which frequently caused others in the skit to break character with laughter.

Early on, Conway and Anderson acted in TV commercials that built on their quirky brand of humor to supplement their income.

Conway also recorded a comedy album with Anderson, who gained national prominence as a voice-over announcer for ABC Television beginning in the 1970s.

Conway also made regular guest appearances at numerous "Ghoulardifest" functions held by WJW over the years, along with former Cleveland TV personality Bob "Hoolihan" Wells, in tribute to Anderson, who died in 1997.

Following his departure from WJW, Conway moved to New York City; where, with Rose Marie's assistance, he auditioned for, and gained a spot on, ABC's The Steve Allen Show as a regular player.

Conway appeared at Borgnine's 90th birthday celebration and, four years later, paid tribute to his friend at the 7th Annual Screen Actors Guild Awards on TNT.

[19] Conway was part of an infamous network TV programming catastrophe, Turn-On, a counter-cultural sketch comedy show on ABC that was derided as a rip-off of NBC's Rowan & Martin's Laugh-In.

Turn-On received enough immediate, negative reaction to force several ABC affiliates, including WEWS-TV in Conway's hometown of Cleveland, to refuse to return to the program after the first commercial break.

Two of Conway's memorable characters on the Burnett Show were The Oldest Man, whose shaggy white hair, slow speech, and shuffling gait ran counter to the much-needed energy levels of the various occupations in which he was usually found, and Mr. Tudball, a businessman whose intentions of running a "ship-shape" office were usually sunk by the bored indifference of his secretary, Mrs. Wiggins (Burnett).

[24] Conway would often make his co-stars on The Carol Burnett Show break character and laugh in the middle of a scene, usually without speaking a line of dialogue.

[26] A prime example of his ability to make his co-stars laugh uncontrollably involved Lyle Waggoner as a captured American airman, with Conway as a stereotypical blond-haired Gestapo agent charged with his interrogation.

In a long, drawn-out fashion, the Hitler puppet (Conway providing a falsetto voice, with German accent) sings "I've Been Working on the Railroad," and with each passing verse, Waggoner loses more of his composure, finally laughing hysterically when puppet-Hitler screeches, "FEE-FI-Fiddely-I-O!".

Conway tells an increasingly absurd story about his visit to the circus; as he continues, the other cast members (Carol Burnett, Vicki Lawrence, and Dick van Dyke) are soon having trouble staying in character, looking away from him and the cameras.

[30] In the spring of 1983, Conway starred in another situation comedy, Ace Crawford, Private Eye; a spoof of detective shows, it lasted only a month.

Dorf also appeared on an episode of Tim Conway's Funny America in the summer of 1990, leading an aerobics class on his impossibly short legs.

In 1996 and 1997, Conway guest-starred in ABC's Coach, for which he received the Primetime Emmy Award for Outstanding Guest Actor in a Comedy Series, playing Kenny Montague in the 1996 episode "The Gardener.

In 1999, Conway and his good friend Ernest Borgnine reunited to become the first guest stars of Nickelodeon's SpongeBob SquarePants, voicing the roles of Mermaid Man and Barnacle Boy.

Series creator Stephen Hillenburg and creative director Derek Drymon visioned the voices of the characters with the two actors in mind from the very beginning, having been fans of their work in McHale's Navy.

From 2001 to 2005, Conway guest-starred in Yes Dear as Tom Warner, the father of Greg, with Carol Burnett Show co-star Vicki Lawrence playing his wife.

[35] In 2016, he played Professor VanVanguard, a knowledgeable character of the lives, characteristics and treating of zombies in the award-winning feature film Chip & Bernie's Zomance.

[citation needed] He won another Emmy Award for Outstanding Guest Actor in a Comedy Series for his role as Bucky Bright in the 30 Rock episode "Subway Hero," which initially aired on April 17, 2008.

Conway appeared as a guest during that first Burnett season and the two men immediately became friends starting a lifetime of working together until Korman's death in 2008.

The DVD Together Again with Tim and Harvey is a recording of their touring stage show that ran over 10 years to sold out markets until Korman's death in 2008.

[41][42][43] When interviewed in 2004, Conway said of Korman, "We're friends; He's a bright guy; he can do The New York Times crossword puzzle in about five minutes, but he can't tie his shoes.

In it, Bixby is tricked into taking care of a trio of orphans as a pair of lovable holdup men named Amos Tucker (Conway) and Theodore Ogelvie (Knotts) attempts to steal a gold nugget the children find.

[56] A fan of thoroughbred horse racing and an occasional racehorse owner, Conway was the co-founder and vice-president of the board of directors of the Don MacBeth Memorial Jockey Fund.

[59] His daughter Kelly and his wife Char both wanted sole conservatorship over his health, and a suit was filed at the Superior Court of Los Angeles.

[3][62] Numerous actors and celebrities paid tribute to Conway following his death, including Dick Van Dyke, Patton Oswalt, Ben Stiller, Billy Gardell, Ed Asner, Buzz Aldrin, Neil Patrick Harris, Tom Kenny, Jamie Lee Curtis, Larry King, Judd Apatow, Wayne Brady, Marlee Matlin, Al Jean, John Scalzi, Richard Lewis, Marsha Warfield, Patricia Heaton, Tony Hale, Larry Wilmore, Vicki Lawrence, Yvette Nicole Brown, Andy Richter, and Conan O'Brien.
