Quotes: Magic A Is Magic A

"Now you might think I'd be all over this shapeshifting business, Paxto, but if comic books, cartoons, and Sci-Fi Original Movies have taught me anything, it's that shapeshifting comes with a bunch of boring rules and restrictions that limit its potential Turn-Into-A-Bulldozer-Whenever-I-Wantity. 'You can turn into a machine gun but not bullets.' 'Contemporary jazz turns you back to normal.' 'You can only turn into presents your grandma's knitted for you.'"
Strong Bad, Homestar Runner (sbemail shapeshifter)

"We don't ask that you stay within the bounds of physics, but at least follow the rules you freaking made up."

"But Magic is as Magic does. Just funny that way."

Y'see, demons can't resurrect people unless a deal's made. I know, red tape, it'll make you nuts.

Roger Ebert, review of Kazaam

"Its very TNG to take something that the Original Series did so naturally (place the weirdest things like Nazis and hippies in the future) and give it a technological reason for happening like the holodeck or because of the power of the Q. This show is far too stuffy to just let these insane things take place simply because. Internal continuity is shot to hell this season as when you leave the holodeck you can bring things like water and lipstick with you…these things are not confined to the hologrid, which surely suggests that anything can walk off the holodeck onto the ship?"
Doc Oho on Star Trek: The Next Generation, "The Big Goodbye"

...but one thing [Speed Racer] did right is that it didn’t bother explaining why Speed Racer lived in this crazy-ass world with these crazy-ass cars driving on crazy-ass racetracks, and also why they had a monkey. The point is that if you start your movie with the premise “this is how things are,” audiences will, more often than not, be fine with that so long as you suspend their disbelief and never question your own narrative.

The natural assumption is that any subject that can be taught to students in such a way that their competence in this subject can be tested by examination is a science.
