In 2005, Dick stirred controversy in Edmonton, Alberta, at Yuk Yuk's comedy club when he dropped his pants and exposed his genitals to the audience. Amid the uproar, he was ushered off the stage and the second night was canceled.
On December 2, 2006, he angered an audience at the Improv Club in Los Angeles by shouting "You're all a bunch of niggers!" following an improvised set with comedian Ian Bagg. This was a direct reference to Michael Richards' use of the same epithet to insult hecklers two weeks earlier. He later issued an apology through his publicist:
“ I chose to make a joke about a subject that is not funny, in an attempt to make light of a serious subject. I have offended a lot of people, and I am sorry for my insensitivity. I wish to apologize to Ian, to the club and its patrons and to anyone who was hurt or offended by my remark. ”
On February 2, 2007, he was forcibly removed during an appearance on Jimmy Kimmel Live, after repeatedly touching guest Ivanka Trump. After Dick rubbed Trump's legs and touched her hair, Jimmy Kimmel begged him to behave himself. When Dick asked Trump to "give him a big, fat, sloppy kiss right on the lips" and grabbed her arm, Kimmel called in two security guards. Kimmel and the guards dragged Dick off-set. On May 2, 2007, he made another appearance on Kimmel, which began by showing the clip of him being dragged out of his previous appearance, and then wheeled out, Hannibal Lecter-style, on a dolly. He exchanged some dialogue and playful touching with Kimmel's other guest, Danica Patrick.
On July 17, 2007, at the Laugh Factory comedy club in Los Angeles, Dick was in an altercation with his former NewsRadio costar Jon Lovitz, who claimed that, a year earlier, Dick had approached him at a restaurant and said, "I put the Phil Hartman hex on you; you're the next one to die," and demanded an apology from Dick. Lovitz has alleged that Dick gave cocaine to Hartman's wife Brynn, a recovering addict, causing her to relapse and five months later, kill her husband in their home before committing suicide. Upon joining the cast of NewsRadio as Hartman's replacement, Lovitz told Dick, "I wouldn't be here now if you hadn't given Brynn that cocaine." Additionally, as reported in TV Guide, Dick was the last person in the company of Suddenly Susan star David Strickland in Las Vegas on March 22, 1999. Strickland was scheduled to report to his drug rehab probation officer on a routine check-in within a day of his death.
In August 2007, Dick was cited by Columbus, Ohio police for urinating on a sidewalk and a building. During his weekend in Columbus he was reported to be intoxicated during his standup performance and groped patrons at a comedy club. Upon his return to Los Angeles, Los Angeles County deputies were called to his residence to respond to a complaint that Dick was throwing beer bottles into his neighbor's yard. He also slapped a reporter in the face outside a Los Angeles nightclub.
On July 16, 2008, Dick was arrested in Murietta, California on suspicion of drug possession and sexual battery. He was arrested for allegedly grabbing and pulling down a 17 year old girl's tank-top and brassiere down, thereby exposing her breasts. During a search of his person, police reported finding a small quantity of marijuana and one Xanax tablet (for which Dick did not have a prescription) in his front pants pocket.
