 Thomson and Thompson (Dupont et Dupond in Hergé's original version) are two incompetent detectives who look like identical twins, their only discernible difference being the shape of their moustaches. First introduced in Cigars of the Pharaoh, they provide much of the comic relief throughout the series, being afflicted with chronic spoonerisms. They are extremely clumsy, thoroughly incompetent, and usually bent on arresting the wrong character. The detectives usually wear bowler hats and carry walking sticks except when sent abroad; during those missions they attempt the national costume of the locality they are visiting, but instead dress in conspicuously stereotypical folkloric attire. The detectives were in part based on Hergé's father Alexis and uncle Léon, identical twins who often took walks together, wearing matching bowler hats while carrying matching walking sticks.
