This is written based on experiences of mine & others. No intention to put anyone to shame. no intention to direct any message to anyone that I know of. This is one random post.
Language: Sarcasm.
Dialect: Direct style.
Level of Sarcasm : Level 1, Mild, Lemon & Herbs. Hahah!
1. Leave the office in the mess so that someone can clean it up.
2. After drinking, leave the cups anywhere you like because you know someone is going to wash it for you. Best part is to leave your cup on someone's table.
3. Blast the music aloud so that everyone knows you love that song. Even better, repeat it for at least 8 times.
4. Leave the overloaded rubbish in the bin so that the next day everyone knows you ate KFC.
5. Use the pen that you borrowed from colleague's table and never return it.

6. Eat up all the delicious cookies from the mini pantry all by yourself.
7. Talk on the phone as loud as you can. Laugh at a high pitch too if you can. Show the world that you are the only happy person living here.
8. Use your colleague's PC and to show appreciation, you change the desktop theme, screensaver, wallpaper. Change the Firefox Personas too!
9. Have some Cheesy Wedges while you type using your colleague's keyboard. After all, sharing is caring. Share some cheesy sticky keys.
10. Update your colleague's Twitter status when he/she left for lunch and forgot to log out. Tweet as nasty as you can.
11. Switch off the modem while your colleague is planning to overtime and do her/his work using the internet connection.
12. Wet the office's toilet seat so that other users have to get more tissues to wipe the seat dry.
13. Leave the toilet bowl without properly dispose any evidence of your big/small/medium businesses. Let people know you are a good businessman/woman. That's your outcome. Your product.
14. Keep tapping on the table according to your favourite rhythm using your fingernails. The louder the better.
15. Keep talking nonstop to your colleague so he/she can't focus on her/his work. At least you have a friend to gossip with.
P/s: I give up putting images for the rest. hahah. XD
