Tinker Toys and K'Nex are stupid.

Legos are where it's at. Although you're not supposed to say Legos...

From 70s/80s Lego catalogues:

"The word LEGO is a brand name and is very special to all of us in the LEGO Group Companies. We would sincerely like your help in keeping it special. Please always refer to our bricks as 'LEGO Bricks or Toys' and not 'LEGOS.' By doing so, you will be helping to protect and preserve a brand of which we are very proud and that stands for quality the world over. Thank you! Susan Williams, Consumer Services."
