Guys,
    They's just gone an' proved whut I been thinkin' fer years.  Here is the Si-en-tificle report to prove it!
DARK SUCKER THEORY

For years it has been believed that electric bulbs emitted light. However, recent information from Bell Labs has proven otherwise. Electric bulbs don't emit light, they suck dark! Thus they now call these bulbs Dark Suckers.
The dark sucker theory, according to a Bell Labs spokes-person, proves the existence of dark, that dark has mass heavier than that of light, and that dark is faster than light.
Explained...

The basis of the dark sucker theory is that electric bulbs suck dark. Take for example, the Dark Suckers in the room where you are. There is less dark right next to them than there is elsewhere. The larger the Dark Sucker, the greater its capacity to suck dark. Dark suckers in a parking lot have a much greater capacity than the ones in this room.
As with all things, dark suckers don't last forever. Once they are full of dark, they can no longer suck. This is proven by the black spot on a full Dark Sucker. A candle is a primitive dark sucker. A new candle has a white wick. You will notice that after the first use, the wick turns black, representing all the dark which has been sucked into it. If you hold a pencil next to the wick of an operating candle, the tip will turn black because it got in the path of the dark flowing into the candle.

Unfortunately, these primitive dark suckers have a very limited range. There are also portable dark suckers, called torches. The bulbs in these can't handle all of the dark by themselves, and must be aided by a dark storage unit. When the dark storage unit is full, it must be either emptied or replaced before the portable dark sucker can operate again.

Dark energy
Dark has mass. When dark goes into a Dark Sucker, friction from this mass generates heat. Thus it is not wise to touch an operating dark sucker. Candles present a special problem, as the dark must travel in the solid wick instead of through glass. This generates a great amount of heat. Thus it can be very dangerous to touch an operating candle.

Dark is also heavier than light. If you swim deeper and deeper under water, you notice it gets slowly darker and darker. When you reach a depth of approximately fifty feet, you are in total darkness. This is because the heavier dark sinks to the bottom of the lake/sea and the lighter light  floats to the top. The immense power of dark can be utilized to mans advantage. We can collect the dark that has settled to the bottom of lakes and push it through turbines, which generate electricity and help push it to the ocean where it may be safely stored.

Speed of Dark
Finally, we can prove that dark is faster than light. If you were to stand in an illuminated room in front of a closed, dark closet, then slowly open the closet door, you would see the light slowly enter the closet, but since the dark is so fast, you would not be able to see the dark leave the closet.

In conclusion, Bell Labs stated that dark suckers make all our lives much easier. So the next time you look at an electric bulb remember that it is indeed a Dark Sucker.
