Pro tip: Mario jumps high enough to kill himself

I've mentioned that Mario in his pre-Mario Bros. days was real fragile. If he fell from much further than he'd fall at the apex of his jump, he's dead, which always seemed harsh to me.

But take this screen from the Donkey Kong arcade game:

You'll notice that there are these two elevators, one going up and one going down

While you're waiting for one to take you to the level you want to go, you might decide that you're bored and play with the buttons to kill time. But, hit the jump button when you're riding the Down elevator...

Suddenly the laws of physics go out the window and Mario jumps his normal height while the floor plummets away from him.

Yep, that means that he's fallen too far and buys himself a new farm.

So, I wouldn't recommend it.
