Pictures of April Fools Day -

A disputed association between April 1 and foolishness is in Geoffrey Chaucer's The Canterbury Tales (1392). In the "Nun's Priest's Tale", a vain cock Chauntecleer is tricked by a fox on Syn March bigan thritty dayes and two. Readers apparently understood this line to mean "32 March", i. e. April 1. [citation needed] However, it is not clear that Chaucer was referencing April 1. Modern scholars believe that there is a copying error in the extant manuscripts and that Chaucer actually wrote, Syn March was gon. If so, the passage would have originally meant 32 days after March, i. e. 2 May, the anniversary of the engagement of King Richard II of England to Anne of Bohemia, which took place in 1381.
