Anyone have any good ones?

Completely fill up a shopping cart and then abandon it when your in line. Set off all the alarm clocks to go off at a certain time. Make up an item with a rediculous name and ask an employee to help you find the item. Say something funny on the intercom ( first watch an employee type in the code and memorize it) If your at wallmart the code is usually #96 or #9611 or #96__

take peoples carts when they arent looking and leave them somewhere else in the store

poison the fish tanks

I saw a video where a guy recorded himself cussing very loudly on a tape, then he brought it into the store and put it into a random stereo, hit play, and ran. It was pretty funny.

get some rats at the pet store and release um in the cereal isle

i like it .........

Record CDs to play sounds that people would not want. Like the cussing or erotic sounds and nonsense. Make a bunch of them and put about 5 or 10 sec of silence so that you can get away. Make the CD player go on repeat. Since there will be people staying in the area or watching cameras you should make multiple CD's and set them to different times. 30 sec 1 min 2 min 5 min, so forth. So that they think they turn it off but there are more

also start crawling on the ground like you are looking for something and if anyone walks by yell at them to stop because you lost your last contact or something. Sounds stupid but is hilarious when you create a back up in the store

go into a part of the store thats empty and take a shit
