Roadrunner and Coyote cartoons defy physics regularly. Not only do RR and Coyote hang in mid air sometimes, but other times the cliffs they stand on hang in mid air while the whole cliff itself falls.
I used to get a kick out of the old 6 Million Dollar Man and Bionic Woman shows. Their bionic legs could make them run 60mph without shattering their fragile hip bones or spine. And their one Bionic arm could lift a car without ripping itself out of their shoulder socket.
In Superman Returns he lifts a whole airplane by its nose. The metal in the skin of that plane must be incredibly dense and structurally reinforced. Also, Superman doesn't get driven into the dirt by the weight of the thing.
Sounds like a fun class.
