Page yourself

Page yourself over the intercom. Don't disguise your voice.

Find out where your boss shops and buy exactly the same outfits. Wear them one day after you boss does. This is especially effective if your boss is of a different gender than you.

Make up nicknames for all your coworkers and refer to them only by these names. "That's a good point, Sparky." "No, I'm sorry, but I'm going to have to disagree with you there, Cha-Cha."

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."

Hi-Lite your shoes. Tell people you haven't lost them as much since you did this.
