Things To Do When You're Bored

See how long you can hold your breath.
(Amusement Potential: 4-20 minutes) Not that much fun, but it sure passes the time. Play with a friend, or try to beat your own personal best. Some tips: hyperventilate before hand, and stay as still as possible. My personal best is 2:00 (exactly).

Try to not think about polar bears.
(Amusement Potential: 1-5 minutes) 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 polar bears anyway.

Scratch yourself.
(Amusement Potential: 1-3 minutes) Go ahead, scratch yourself now. Even if nothing itches, go ahead. Doesn't that feel pretty good?

Try to swallow your tongue.
(Amusement Potential: 1-3 minutes) There's not much to say about this one. It is possible.

Get yourself as nauseated as possible.
(Amusement Potential: 5-10 minutes) 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.
