Can I use RCX sensors and motors with the NXT brick?
I have a bunch of motors and sensors from the original Mindstorms set. It seems a shame I can't use these with the more recent NXT set. Are there any unofficial modifications that allow you to convert the cables?

Why does the Erling brick have a ridge below its outward facing stud?
Why does the Erling brick (#4070) have a ridge below its outward facing stud?
Whereas the more versatile and less common #87087 does not? The #87087 piece also has a better use in SNOT usage, as it can accomadate larger bricks.

For LEGO's board game line, they have moulded a LEGO die, with a 2x2 stud pattern on each side.

Why did Lego use the same number for two different sets?
For example, Ricky Racoon on his Scooter from 1979 is a completely different set from House with Garage from 1996, but they share the same number (324). Why did Lego recycle numbers like this? Do they contunue to re-use old numbers?

Why are minifigure wrenches tapered at the end?
The common minifigure wrench is tapered at one end. Why? None of the other minifigure tools are shaped this way. Is the wrench meant to also serve as a minifigure pry bar? Or perhaps as some sort of flathead screwdriver?

Why do official Lego sets sometimes use 1 large part when several would work just as well?
One of the things that makes Lego so great is the ability to rebuild sets into something new and different. However, I know that sometimes TLG uses large pieces to lower costs and/or build complexity. Some examples:
