10. A "baby monitor." Makes those closed door meetings easier to hear.

9. A pregnancy test kit with a positive result and an unsigned note saying, "I told you that damn condom ripped."

8. Put a piece of tape on the underside of his mouse. That way the ball doesn't roll and it will take the jerk and the IS department all day to figure it out.

7. 32 beepers, all stashed in different places. Borrow them from managers who are forced to wear them 24 hours a day. Page a different beeper every 15 minutes. This works especially well if you also switch his morning decaf with espresso.

6. First, simply hide pot seeds and watch as your clueless boss waters and nutures the plants daily. Second, watch as boss is escorted out of the building three months later by security.

5. Thong, lace bra the morning after the company Christmas party.

4. Nonchalantly drop lingerie and then kick it under the front of his desk (where he can't see it, but visitors can) early in the morning before an important meeting. Then, during the meeting, stare quizzically at the floor under his desk.

3. A memo from Accounting Department requesting a meeting to review his recent purchases on the company credit card?

2. An open and empty condom wrapper.

And the number one fun thing to hide in your boss's office...

1. A stained dress.
