In the early 1980s, Arnold had a prop-based comedy routine called "Tom Arnold and the Goldfish Review."
Roseanne Barr brought him in as a writer for her television sitcom,
Roseanne. He married her in 1990, after she divorced her first husband. Arnold wrote himself into the show as the character "Arnie Thomas". The couple's marriage attracted media and especially
tabloid attention due to their sometimes outrageous behavior. In 1992, Arnold starred in his own sitcom,
The Jackie Thomas Show. Airing after
Roseanne on ABC, the show lasted 18 episodes. In 1993, Arnold and Barr bought a house together in the town of Eldon, Iowa and opened a restaurant, 'Roseanne and Tom's Big Food Diner' nearby. The diner served
loosemeat sandwiches similar to the specialty of the fictional Lanford Lunch Box on
Roseanne, which in turn was based on the real-life
Canteen Lunch in the Alley in Ottumwa. Both appeared in the 1993 movie
The Woman Who Loved Elvis, filmed in Ottumwa. In 1994, Arnold appeared as the
sidekick to
Arnold Schwarzenegger's character in
James Cameron's action blockbuster film
True Lies. Arnold and Barr divorced in 1994 due to irreconcilable differences. Their restaurant closed in 1995. After Arnold's divorce from Barr, he narrated and starred in several Craftmatic Adjustable Bed commercials that aired throughout 1995. The last commercial that he filmed culminated in Arnold lying in a bed that caught on fire and melted a strand of his underarm hair during the taping; the footage was never released. Arnold commented on Twitter in 2014: "Me and Mike (he was one of my best friends) used to laugh about how [I] had a
Pepsi commercial of my own". In November 2000, Arnold played the role of Al Raymond in the second-season
Baywatch Hawaii episode, "The Cage". In a late 1990s interview on radio's
The Howard Stern Show, Arnold admitted that his share of his and Barr's estate amounted to "over $20,000,000", including a percentage of the
Roseanne ABC-TV series, but would not elaborate, citing a confidentiality clause. From 2001 through 2005, he was one of the hosts of
The Best Damn Sports Show Period. From 2003 to 2005, Arnold was the voice of
Arby's "
Oven Mitt" commercials. Arnold had his first romantic leading man part in the 2005 movie
Happy Endings. That same year, Arnold starred in
The Kid & I. From 2008 to 2011, he hosted the
CMT show
My Big Redneck Wedding. He hosted CMT's
The Biggest Redneck Wedding Ever in 2008, in which he served as the wedding planner, created a wedding that exceeded the dreams of a couple who wanted to be married in a mud bog, and performed the actual ceremony. CMT also made three series of "My Big Redneck Vacation" presented by Arnold and featuring the Clampet Family from
Shreveport, Louisiana. Arnold's role as a child molester in
Gardens of the Night sparked revelations that he had been a victim of sexual abuse in his childhood. He decided to take on the role to shed more light on the issue. In January 2017, Tom Arnold was revealed as a celebrity contestant on the Australian edition of ''
I'm A Celebrity...Get Me Out of Here!''. He was the first evictee from the jungle, after 17 days, and stated he was paid between $US600,000 and $US700,000 for his participation in the program. In June 2017, Arnold filed a lawsuit against companies
Network Ten and 'A List Entertainment' for defrauding him for being on ''I'm a Celebrity...Get Me Out of Here!''. Arnold claims that he was promised a payment of $425,000 and a comedy tour in Australia. However, he was missing $140,000 in payment and Network Ten backed out of the comedy tour. In 2018, Arnold's
Viceland show
The Hunt for the Trump Tapes premiered to low ratings and mainly negative reviews. The show was canceled after one season. ==Personal life==
