I found this via Japundit. As a former Anime Club president, I must say that not only is this list hilarious, but it's very true.
Here are some of my favorites:
#4 - Law of Constant Thrust, First Law of Anime Motion: In space, constant thrust equals constant velocity.
#9 - Law of Dramatic Emphasis: Scenes involving extreme amounts of action are depicted with either still-frames or black screens with a slash of bright color (usually red or white).
#15 - Law of Inexhaustability: No one *EVER* runs out of ammunition. That is of course unless they are cornered, out-numbered, out-classed, and unconscious.
#18 - Law of Hemoglobin Capacity: The human body contains over 12 gallons of blood. Sometimes more.
