This is a hack, as found on thereifixedit.com.
Actually about everything on that site is a hack.
Hacks are ingenious and audacious uses of some things out of their context.
The beauty of a hack consists in the fact, that you have a given problem and tools that were never intended to solve it, but you solve the problem with just those tools (instead of getting the right ones). They are clever, fast and fun. The downside is, that the results are often fragile and dangerous to use for outsiders.
I mean, if you like solving your problems as in the picture, there's no problem. The problem occurs, when you solve other people's problems like that. In this case, they would probably get electrocuted or burned or something.
In software development, you want that your code can be handled by others (which includes your future you) without the equivalent of a fatal injury. As Dijkstra put it:
The competent programmer is fully
aware of the limited size of his own
skull. He therefore approaches his
task with full humility, and avoids
clever tricks like the plague.
And hacks are among the most clever tricks.
Hacks are ticking time bombs somewhere in your code, because the common ones are inherently based an too many assumptions ("just doing it" is preferred to proper decoupling). As soon as those assumptions no longer hold, your whole system can break down without you having any idea what happened.
