#2 April Fools Day

Aside from April Fools' Day, the custom of setting aside a day for the playing of harmless pranks upon one's neighbour has historically been relatively common in the world. In popular culture Books, films, telemovies and television episodes have used April Fool's Day as their title or inspiration. Examples include Bryce Courtenay's novel April Fool's Day (1993), whose title refers to the day Courtenay's son died. The 1990s sitcom Roseanne featured an episode titled "April Fools' Day". This turned out to be intentionally misleading, as the episode was about Tax Day in the United States on April 15 the last day to submit the previous year's tax information.
