Sorry, but you link didnt work for me. (the editable wiki scripts.)
Sooo heres what i was gonna put in there...
1) Get a pair of Latex gloves that doctors use, go to the bank and when you're waiting in line nudge the person in front of you lightly in the back. When they turn around and look at you start putting the gloves on and say "Now would be a good time to leave".
2) Go to an airport, find a person just sitting somewhere waiting for their flight and stand about 10 feet in front of them. Just stare at them until they stop what their doing and look up at you (DO NOT LAUGH OR ANYHTING LIKE THAT). Say "Don't get on the plane" then just turn around and WALK away. You know the person will probably be thinking "I wonder if I should get on the plane".
3) Go to a fast food resturuant. Go inside, and when it's your turn to order, say "Just a second" to the cashier then look at the menu, POINT at the menu and order something that doesn't exsist on the menu. The cashier will acutually look at the menu almost everytime.
