Push your eyes for a cool light show
See a variety of blobs, stars and flashes. Try to make out things-is your subconcious trying to send you a message? Can you control what you see by pressing different areas with different forces?

Try not to think about pink elephants
This is especially hard, because by trying too much, you remember what you were trying to avoid thinking of. If you try too little, you end up thinking about them anyway.

Hurt yourself (or someone else)
What is pain? There's nothing physical about it-it's all in your mind. Besides, after pinching yourself for a while, boredom will seem nice next to being in pain.

Try to swallow your toungue.
There's not much to say about this one. It is possible i guess.  Course you'd probably die.... but well..........   nevermind.

Look at something for awhile, shut your eyes, enjoy the after image
It takes about 30 seconds of staring to create an after image, and the image is then viewable for about the same length of time. It works the best if you stare at lights.  It's fun to combine this one with pushing on your eyes.

Get yourself as nauseated as possible
Best achieved by looking straight up and spinning around. Try to be so dizzy you can't even stand up. This is also entertaining due to the "makes boredom seem a lot better" effect.  I used to play this game a lot with my friends when i was little.  The object is to see how long you can play without throwing up.  I used to see people dressed in white suits coming toward me while i was spinning.  Kinda freaked me out so i stopped.  Still a great game though.

Watch chinese movies on the international channel
This is SO MUCH FUN!  You'd be surprised at some of the stuff they show.  Last weekend i was watching this movie about this girl who was being chased around by a bunch of lesbians.  It was hillarious!

Mess with telemarketers
Very entertaining.  There might be a link on here in the near future to some of the fun things you could do to them.

Pretend you were a millionair and were about to die
Who could you really trust?  Would people be concerned that you were going to die or would they just want your money?  Hmmmmmmmmmm................

Step off curb with eyes shut, and pretend it's a cliff
To get any benefit out of this one, you have to have a good imagination. Don't step off imediatly, build up to the jump.  Feel the winds at that altitude. Step off and... Aaaaahhh!!  (not recommened for poeple who live on highways)

Burn things with a magnifying glass
Ants are always fun to use for this, but buring the foot of someone you don't like can be just as amusing. Try to set your shoe on fire.  See if you can burn your house down.

Stare at the back of someone's head until they turn around
This works on the "i have the feeling I'm being watched" principle. Does this really work?  Can people actually tell whether or not they're being watched?  I think so, but wouldn't that mean that everyone has a bit of ESP in them?

Have a "who is less competitive" competition
Trying to win at this will make you lose. Trying to win makes you lose which makes you win. Not trying at all makes you lose which makes you win which makes you lose.

Pick up a dog so it can see things from your point of view
Think about it: your dog has only seen the house from a viewpoint from 6" to 2' high. It's never seen the tops of counters, what you keep on the desk, the tops of shelves, etc. Try looking at things from it's point of view, too.

Pull out hair, stick it in someone's ear
Best done to sleeping people. Add challenge in having no one else around, because then you can't blame it on anyone else.  Be prepared to run though if you do it to a really large man.

Pour water in hand, make sneeze noise, throw water on back of person's neck
Always good fun. For an even bigger reaction out of the person, act like your not sorry at all for what they think you did. Comment instead on how big that sneeze was or about how there was a lot of mucus in that one.  You can even add to the fun by throwing stuff thats not water at them.  Like chicken soup or macaroni and cheese or something.
