Thomson and Thompson (French: Dupont et Dupond [dy.pɔ̃])[1] are fictional characters in The Adventures of Tintin, the comics series by Belgian cartoonist Hergé. They are two incompetent detectives who provide much of the comic relief throughout the series. While their different (albeit similar) surnames would suggest they are unrelated, they look like identical twins whose only discernible difference is the shape of their moustaches.[2] They are afflicted with chronic spoonerisms, are extremely clumsy, thoroughly clueless, and usually intent on arresting the wrong character. In spite of this, they somehow are entrusted with delicate missions.
The detective with the flat, drooping walrus moustache is Thompson and introduces himself as "Thompson, with a 'P', as in psychology" (or "Philadelphia", or any such word in which the "P" is silent), while the detective with the flared, pointed moustache is Thomson, who often introduces himself as "Thomson, without a 'P', as in Venezuela."
Often, when one says something, the other adds "To be precise" (Je dirais même plus), but then repeats what the first said, only twisted around.[3] This trait has gained popularity.
Thomson and Thompson usually wear bowler hats and carry walking sticks, except when abroad: during these missions they insist on wearing the stereotypical costume of the country they are visiting, hoping to blend into the local population, but instead manage to dress in folkloric attire that actually makes them stand apart.
The detectives were in part based on Hergé's father and uncle, identical twins who wore matching bowler hats while carrying matching walking sticks.[4]
