Office email pranks are usually done on the occasion of April fool’s Day or during holidays, when the atmosphere is jovial and informal. It is usually played among team members or a selected group of people and doesn’t involve higher authorities. Here are some examples of office prank emails:
An email with a serious subject may be sent to employees and when they open the mail or attachment, a funny cartoon or joke may pop up, ridiculing the original subject. Or, send a mail saying a holiday has been declared and then break the news that it was just a joke. You can also send a mail to juniors saying the boss is angry with them and wants to see them, only to later reveal that you were having some harmless fun.
Lastly, be sure to play office pranks only on people who can be a sport or else it may backfire and you may be fired!
