Just spent a few minutes reading about Legos. Actually part of what I read is a discussion about how you should say Lego or Lego building bricks, but never the word Legos, as it's not proper method of pluralization. Supposedly the company wanted to protect their trademark and that's easier to do with an adjective, so the proper wording should always be Lego something, be it building bricks, kits, whatever.

Anyway, now I miss my Legos and want to get one of the big sets so I can spend an afternoon playing.
