1. You’re Bored Let’s face it, the best reason to do a prank is because you’re bored. What better way to break up your own monotonous work?
2. They’re Your Boss Pranking your boss let’s you get that one sweet moment of dominance over them that you’ll likely never have otherwise. Of course, be wary of those bosses who may not be so thrilled with your prank.
3. They’re a Jerk and Deserve it Let’s face it, sometimes a coworker is just begging to be pranked. Give that mean coworker a good pranking and you’ll feel all better… for awhile at least.
4. Prank Revenge Perhaps one of the most common reasons to prank a coworker is because you were already pranked by them. But pranking back you can start a prank war that escalate in hilarity and fun!
5. They need cheering up Perhaps you’ve got a coworker who’s just way too stressed out. Sometimes all a person needs is a good prank to get them motivated again. If the prank is done with good intentions, your coworker may just thank you for it.

All you have to do is buy someone a lotto ticket today and tomorrow go out early and buy another ticket with the exact same numbers as the winning ticket from yesterday. When the victim of your prank isn't paying attention swap the newer ticket with the old one. When the person looks in the paper for the winning numbers, he or she won't even realize the date is wrong on the ticket and will believe it is the big winner.
7. Pretend to be someone else on the phone.
