When there's only one other person in the elvator, tap them on the shoulder and then pretend it wasn't you. Push the buttons and pretend they give you a shock. Smile, and go back for more. Ask if you can push the button for other people, but push the wrong ones. Call the Psychic Hotline from your cell phone and ask if they know what floor your on. \ Hold the doors open and say your waiting for a friend. After a while, let the doors close, and say, "Hi Greg. How's your day been?" Drop a pen and wait until someone goes to pick it up, then scream, "That's mine!" Bring a camera and take pictures of everyone in the elevator. Move your desk into the elevator and whenever anyone gets on, ask if they have an apointment. Lay down the twister mat and ask people if they would like to play. Leave a box in the corner, and when someone gets on, ask them if they can hear ticking. Pretend you are a flight attendant and review emergency procedures and exits with the passengers. Ask, "Did you feel that?" Stand really close to someone, sniffing them occasionally. When the doors close, announce to the others, "It's okay, don't panic, they open again!" Swat at flies that don't exist. Tell people that you can see their aura. Call out, "Group Hug!"and then enforce it. Grimace painfully while smacking your forehead and muttering, "Shut up, all of you, just shut up!" Crack open your briefcase or purse, and while peering inside, ask, "Got enough air in there?" Stand silently and motionless in the corner, facing the wall, without getting off.
