Sleep...
I used to work in one of those prefabricated office environments.. plastic people and cheap partition walls. My chair backed up to a partition which connected to the door, and every time someone opened the door the wall would belt me on the back of the head as it shuddered on it's flimsy frame... but I found a way to love that wall.

1. Apply sunglasses to eyes
2. Place pencil in hand and position (tip down) on a pad in front of you.
3. Tip chair subtely back on 2 legs so that head is rested against the partition wall.
4. Go to sleep.

Any time someone came in the room I would be flung forwards as I awoke... and would immediately start furiously writing fractions and other complicated stuff on the pad - thereby appearing far too busy to be interupted!!
