Joe Mentalino was a criminal who worked for Nicholas Andre, and the tertiary antagonist of the 1994 film Dumb and Dumber. He suffered from digestive problems.

He is portrayed by Mike Starr.


In 1994, Joe was tasked with eliminating Lloyd Christmas and Harry Dunne. He posed as a hitchhiker & traveled with them for a while.

At a diner, he planned to spike Harry and Lloyd with rat poison to have control of the briefcase containing the ransom money. He later changes his mind on killing them when he learns that they do not know what is in the briefcase, or the woman it belongs to & eats lunch with them. Not knowing about Joe’s peptic ulcer disease, Lloyd and Harry retaliate for a previous prank by filling his burger with atomic peppers. Peppers are known irritants to the lining of the stomach. With a large bite of atomic peppers, anyone with an already existing condition of peptic ulcer disease would likely experience excruciating pain within seconds. Symptoms of peptic ulcer disease may present similarly to that of a heart attack (abdominal pain, nausea, sweating, impending doom). He collapses holding onto his stomach & requests his pills for his ulcer.

Harry, who found the rat poison pills in Joe’s jacket pocket, believed it to be the medicine & gave it to Joe, who had barely seconds to realize what he was given by Harry. With his last breath & last words, he blames Harry for it & calls him an “SOB” & then gurgles and collapses down dead.


Joe was a cold-hearted killer & would murder without hesitation. This was shown when he decapitated Petey. He also had a bad temper & punched a man who was annoying him straight through a phone box. His impatience was especially displayed when he was travelling with Harry and Lloyd, who irritated him with their stupidity.
