The Laughing Salesman

is a Japanese manga series created by Fujiko Fujio. The manga began as a one-shot series serialized in Shogakukan's Big Comic magazine on 1968, later becoming a full-fledged series published by Jitsugyo no Nihon Sha's Manga Sunday magazine from 1969 to 1971.

It is notable in Japan as the only series by the duo, Hiroshi Fujimoto and Motoo Abiko, to be darker and more mature in its themes than their previous works. An anime adaptation was produced by Shin-Ei Animation, directed by Toshirō Kuni and written by Yasuo Tanami. It aired on TBS from October 10, 1989 to December 28, 1993 with a total of 127 episodes. A second anime adaptation was announced and aired on Tokyo MX from April 3 to June 19, 2017.

Plot
Society is filled with people who struggle through their lives or never achieved their goals. The stories in the series focus on individuals who meet a shadowy and ominous salesman called Moguro Fukuzou. Moguro promises to "fill your empty soul" and give them a better life, if they follow his advice or agree to his conditions. However, once Moguro's clients begin to enjoy the fruits of their new life, they often breach their conditions, betray his trust, or deny that they received assistance at all. When this invariably happens due to their avarice, greed or selfishness, Moguro punishes his clients by using their reliance on his aid against them. With their lives ruined, he believes that they have been justly rewarded and he looks for more potential clients that he can help in a similar way.
