The answer I've heard the most (with a source citing the official confirmation) is that green, brown and gray bricks were omitted from the LEGO palette because the company wanted to discourage kids from building tanks, planes, and other realistic military hardware.
Early LEGO colors were inspired by the work of Mondriaan, which mainly consists of white, black, red, blue and yellow. These primary colors were considered to be most appealing to kids.
From the book “Brick by Brick”:
The new product was patented in 1958 and within a few years bright
yellow, red and blue Lego bricks, colours inspired by the paintings ...
Further to Alex's answer, from that source I found eleven colours that only lasted a year:
Fabuland Orange 1983
Very Light Orange 2000
Clikits Lavender 2005
Chrome Black 2009
Chrome Green 1999
Satin White 2020
Satin Trans-Light Blue 2020
Satin Trans-Dark Pink 2020
Glitter Trns-Orange 2020
Speckle Black-Copper 2006
Speckle DBGray-Silver 2006
Of course the ...
According to Bricklink, Very Light Orange was only used by single part for one year only - in 2000. It was used in 2 sets (Scala and Belville) and 1 "gear".
That part is this cat:
Another color is Clikits Lavender used by a number of parts (9, to be precise) for Clikits theme and these were produced in 2005.

A practical engineering concern could be a reason to limit the colours used for molding in ABS plastic.
The colourant added to the base plastic can affect the physical properties of the molded part. Depending on how tight the dimensional tolerances are for the finished part a separate mold may be required for each colour.
Perhaps the Lego group process ...
I have a background in precision injection moulding, although not to the extremely tight tolerances of Lego. Here's why a manufacturer would try to reduce the number of colours they used, particularly in the old days.

Why design the core monorail hardware this way?
This is hard to answer without a degree of speculation, but I assume that the core reason behind the decision to design the monorail this way likely came down to cost and engineering challenges. TLG wanted to allow for a monorail train to be able to navigate inclines effectively. This required:
A cog system
LEGO does not directly create military sets.
A LEGO representative gave the following reason:
Are there any chances that Lego will ever start producing modern day warfare Lego, with tanks and helicopters and what not?
We have a strict policy regarding military models, and therefore, we do not produce tanks, helicopters, etc. While we always support ...
I asked Gary Istok on your behalf in this Brickset Forum thread, who is an expert on LEGO's history. He said the following:
When LEGO replaced the Cellulose Acetate bricks circa 1963 with ABS
plastic for non-trans parts, and polycarbonate for the trans ones,
they had a problem with the red and yellow parts. For some reason

You can find some of The LEGO Group's financial information in their annual report. Note that the financials are in Danish kroner, so you'll need to do some currency conversion. For example, the net profit for 2012 was 5.6 billion DKK, which works out to about 1 billion USD.

So far, the best I can think of is the red classic space guy which appeared in 46 sets.
Considering minifigs were less specialized back then, I bet the winner is in that time period anyway, and the fact that spacemen wore an uniform makes me think there is no other minifig apperaing in 46 sets. Even the basic city worker only reaches a pale 21 sets.
The official story is that Ole Kirk Kristiansen didn't realise until years after naming the company what it meant in Latin (normally it's said to mean "I put together", not "I collect"), and as there was no construction over the products made in the first many years, it seems unlikely that he should have thought along those lines.

Not really an answer, just a small point of fact..... There were actually 4 Monorail Trains planned, a Futuron Space-Themed one, a Unitron Space-Themed one, the ever pleasant Airport Shuttle Town-Themed one, (good for cities, even by today's standards, as building a large scale Monorail using brick-build tracks and Power Functions is a little too labor ...
Page was owner of the patent only for Great Britain, allowing LEGO to use the design worldwide. Buying a "rival" company (Kiddicraft) later on is nothing unusual in business history. Therefore, blaming Page's death on LEGO does not make much sense.

Every Lego wooden duck I have seen, whether in person or on the internet, is sitting on a platform with the wheels attached to the platform. This is the original version:
Here is a later version:
Are there any markings on the toy itself that lead you to believe it is a Lego product?
If you look at the quantity of parts in all sets, the most common is the 1x2 brick ignoring color. The most common part and color combo is the Techhnic pin with friction in black.
These stats were pulled from Rebrickable's database - they previously had a "Stats" page, but this has since been replaced with their API.
It does not seem as if it would ever be possible to come to a definitive assertion—or even a sufficiently precise approximation—of "how many LEGO bricks exists." For the English Wikipedia article "Lego" in the "Manufacturing" section informs,
Annual production of Lego bricks averages approximately 36 billion, or about 1140 elements per second.

There have been Christmas-themed sets for a long time, for example set 246-2 Santa and Sleigh from 1977.
Scrolling through all LEGO sets on Brickset, starting from 1949, shows that this is also the first set in their records that is Christmas themed, together with the (likely unreleased) two Santas set 245-2.
While the current plastic Lego "guns" are generally more tame (blasters, pirate pistols), that was not the case with wooden toys from the 1940's including this machine gun from 1945. It's about 18" long and makes a rat-tat-tat sound when turning the crank.
I can't find a link to substantiate this, but a quality assurance representative from LEGO mentioned at a BrickWorld presentation a few years ago that worn out molds are buried on the factory property in Denmark in concrete. If anyone else can find substantiation for that, I'd love to see it.
