The Calculus Affair
In "The Calculus Affair" Hergé introduced Jolyon Wagg, a Belgian insurance salesman, who appeared in each subsequent adventure with the exception of "Tintin in Tibet". Jolyon Wagg was intended as "the proverbial bore", who provides comic relief by repeatedly annoying Captain Haddock and inviting himself to Marlinspike. For the name, Séraphin Lampion in the original French version, Hergé initially chose "Crampon", which was derived from the French expression "Quel crampon!" (English: "What a leech!"), but ultimately preferred the less explicit and harsh-sounding "Lampion". Lampion's insurance company was "Assurances Mondass", which in the English translation became the Rock Bottom Insurance Company.
