Um, I REALLY hope you are kidding.
You should never bottle with the beer falling into the bottle, like through the spigot, rather you should use a wand or a length of hose to fill from the bottom of the bottle upwards.
The reason for this is two fold, first by letting the beer fall into the bottle you are pretty much guaranteeing that you will oxidize your beer. Since there's no way to avoid the fact that your beer is falling THROUGH all the air in the bottle. Oxygen + Fermented beer = LIQUID CARDBOARD. So if you like liquid cardboard, then yeah, it's probably not all that necessary....
Secondly by filling from the bottom up, you are actually pushing the oxygen out the top of the bottle as the beer (with it's co2 already in solution) rises up the column of the bottle.
That's also why you let the beer actually spill out a little above the rim, AND you don't cap for a few minutes. This allows the co2 to help void out any air in the bottle.
Thirdly it also allows for the correct amount of headspace in the bottle.
If you don't have a wand and still insist on bottling get a length of hose to attach to your spigot, that will allow you to still fill from the bottom up. It will by filling the beer up to the top and pulling the hose out of the bottle set the proper headspace which is about an inch to an inch and a half from the crown.
