First, words of caution: Use your discretion. You know your audience better than I! In no particular order:

• Page yourself over the intercom. Don’t disguise your voice.

• Put mosquito netting around your work area and play tropical sounds all day.

• Call in sick. From your cubicle.

• Every time someone asks you to do something, anything, ask if they want fries with that.

• Put your garbage can on your desk and label it “IN”.

• Put decaf in the coffee maker for 3 weeks. Once everyone has gotten over their caffeine addictions, switch to espresso.

• Finish all your sentences with “In accordance with the Prophecy.”

• Don’t use any punctuation.

• As often as possible, skip rather than walk.

• Specify that your drive-through order is “to go.”

• Sing along at the opera.

• Go to a poetry recital and ask why the poems don’t rhyme.

• When the money comes out of the ATM, scream “I Won, I Won!”

• When leaving the zoo, start running towards the parking lot, yelling “Run for your lives, they’re loose!”

• The minute the elevator doors close, yell, “God, what IS that??” Look at people accusingly.

• Tell your children over dinner, “Due to the economy, we are going to have to let one of you go.”

• Encourage your colleagues to join you in a little synchronized chair-dancing.

• Feign an unnatural and hysterical fear of staplers.

• Send e-mail to the rest of the company telling them exactly what you’re doing. For example: “If anyone needs me, I’ll be in the bathroom.”

• Send e-mail back and forth to yourself engaging yourself in an intellectual debate. Forward the mail to a co-worker and ask her to settle the disagreement.

• Send e-mail messages saying there’s free pizza or donuts or cake in the lunch room. When people drift back to work complaining that they found none, lean back, pat your stomach and say, “Oh you’ve got to be faster than that.”

• While sitting at your desk, soak your fingers in Palmolive liquid. Call everyone Madge.

• Put a chair facing a printer. Sit there all day and tell people you’re waiting for your document.

• Order a Diet Water whenever you go out to eat, with a serious Face.

• And The Final Way To Keep A Healthy Level Of Insanity: Laugh often and much, and for no reason whatsoever. This is called therapy.
