A Lego brick, some Lego, three Lego bricks.

Try it with something else. e.g. A Sony television, some Sony televisions, three Sony televisions.

I think the difference is that we do not call a single piece a Lego in the same way that we would not refer to a television as just a Sony.

All US vs. British English things are weird!
