Call AOL and make up a problem that you seem to be having with you AOL. (IE Ever time I sign on a message comes up that says "Problem with your Johnson's rod, please restart AOL) See how long it takes them to realizes your lying, when they call you liar tell them you want to speak to the manager, then hang up.
Call people you don't know up and say "I'm sorry We have to brake up" Then hang up on them.
Goto the local Gap and yell "Who the hell buys all this crap any way." Then walk out.
Walk into your local Sears and do the same thing.
Goto your local Blockbuster, and ask them if they have fake movie names (IE Pig and Dog go to New York) Do this for a while then get mad at them and run out screaming you people have NO good movies!
Gather up all the neighborhood cats, then put them in front of someone's door. Knock on the door and then run.
Goto the Local McD's and ask for fake items (IE Rat Mcnuggets) Try find a new employee and then yell at them when they can't find your order on there computer cash register. Demand to see his/her manager and then run for it.
Goto your Local Church and walk in. Walk up to the altar and pretend you are leading some kind of satanic mass. When the persist comes up to ask you what you are doing his at him and talk like your possessed, see where it goes from there.
Call 911 and tell them a squirrel just set your house on fire, see what happens...
Goto your local Wall and get as many CD's as you can. Then bring them up to the counter. When the clerk rings them in pretend like you dropped something. Bend down to get it and sneak away.
Call people up and talk dirty to them (IE when they pick up the phone and say "hello" say "Hey big guy what are you doing? I'm home alone and totally nude" It works best if your female.)
Get the phone book and call people at random, when they pick up the phone leave some kind of Erie message (IE The calls are coming from inside the house, or the end is near or he's on to you) Then hang up.
