The people at K'NEX believe that their toys are unique and worthwhile, that they are capable of enriching the lives of those who use it, both through pure enjoyment and through its educational impact. So next time your mom is yelling up to you to "stop playing with those silly things and come downstairs for dinner", you can say to her, "stick that in your pipe and smoke it." But maybe not in those exact words because you'd probably be in big trouble.
