I have selected a few that I think are Fun:
2- Answer the phone with an arbitrary question.
4- Put things which couldn't possibly be mailed in people’s mailboxes, like a glass of water, or a bowl of popcorn. Write the address on it and attach proper postage.
19- Stop a conversation with “Wait a second…”, and then see how long it takes someone to butt in. Act incredulous when they ask why you said it. Insist you never did.
39- If you’re alone in a room and someone else enters, immediately leave and do something else, for example getting a glass of water. If they talk to you, talk normally. Continue doing this for a week.
49- Put pictures of baby goats in your wallet. Approach people and ask them if they want to see pictures of your kids.
55- Crazy glue a fake eye to the bottom of a coffee cup, then offer someone a cupof coffee.
56- Glue a coin onto a hard ﬂoor in an area that has a lot of traffic.
68-Wear a wig and refuse to answer to your own name. If your coworkers absolutely need to speak to you, take the wig off and say, “Whoa, where did you come from?
80- Take a sharpie and paper and make facial expressions for everyday objects.
93- Name other coworkers cubicle svarious cities, and start waging war.
