Passive Solutions (How to get rid of...)

People coming into your office-
Eat salads with goat cheese, feta, or asiago at your desk. Tuna and Balsamic vinigrette increase effectiveness.

Strange men talking to you at vending machines/smoking area/elevator-
Casually mention your exhusband, or better yet, your first, second, or third ex-husband (fictitious or otherwise).

Peeping Tom-
Pick your nose by the window (warning: not reccomended in the case of paparazzi)

Strange man following you in the mall-
Crop dust (ie, just eat a white castle and "blow as you go", toots)
