[00:14.18]to make a fool of someone else and laugh at them.
[00:17.39]There are lots of theories surrounding the origins of the day,
[00:22.02]but one explanation is connected with the change
[00:25.67]in the calendar in the 16th century,
[00:28.32]which meant that 1st April

[00:33.16]Those who still celebrated the New Year
[00:36.52]on 1st April were called fools.

[00:47.51]that you can play on your friends.
[00:49.99]For example, you could wear a black sweater
[00:53.41]and pull a piece of white thread through it,
[00:55.95]so that people try to pull it off.
[00:58.04]You could change the time on someone's alarm clock
