The most popular Russian show-business people from Odessa are Yakov Smirnoff (comedian), Mikhail Zhvanetsky (legendary humorist writer, who began his career as port engineer) and Roman Kartsev (comedian). Their success in 1970s contributed to Odessa's status of a "capital of Soviet humour". Later several humour festivals were established in the city, including the celebration of the April Fools' Day.
