Set all the alarm clocks to go off at ten minute intervals throughout the day.
Run up to an employee (preferably a male) while squeezing your legs together and practically yell at him "I need some tampons." (Extra points for this one if you're male.)
Try on bras over top of your clothes.
Make a trail of orange juice on the ground, leading to the rest rooms.
While walking around the store, sing in your loudest voice possible "I smell sex and candy"
Walk up to an employee and tell him in an official tone, "I think we've got a Code 3 in Homewares," and see what happens.

Re-dress the mannequins as you see fit.
Test the fishing rods and see what you can "catch" from the other aisles.

Set up a tent in the camping department; tell others you'll only invite them in if they bring pillows >from another aisle.

Nonchalantly "test" the brushes and combs in Cosmetics.
When someone asks if you need help, begin to cry loudly: "Why won't you people just leave me alone?"
Look right into the security camera, and use it as a mirror while you pick your nose.
Take up an entire aisle in Toys by setting up a full scale battlefield with G.I. Joes vs. the X-Men.
While handling knives in the Outdoors section, suddenly ask the attendant if he knows where the anti-depressants are.

Dart around suspiciously while humming the theme from "Mission Impossible."
Set up a "Valet Parking" sign in front of the store.
In the auto department, practice your "Gaultieresque-Madonna" look with various funnels.
Hide in the clothing racks and when people browse through, say things like "Pick me!!, Pick me!!".
When an announcement comes over the loudspeaker, assume the foetal position and scream, "No, no! It's those voices again!"
Go to an empty checkout stand and try to check people out.
Drag a lounge chair on display over to the magazines and relax.
If the store has a food court, buy a soft drink; explain that you don't get out much, and ask if they can put a little umbrella in it.
