>Whoever doesn't live in the glass-house?<

Reminds me of the African chief (I forget his full name), who fell in love with not only numerous African women but also Western style furniture. So he bought each of his numerous wives an imposing chair to sit in on state occasions. And an even more imposing one for himself, of course - a vertiable monument of carved and inlaid wood.
All went well until his love for his numerous wives led to numerous children, so many that there was no room in the house! The chieftain sadly decided that he would have to move some of the furniture out, but he couldn't bear the thought of parting with it. He puzzled and puzzled over this, then at last struck on another Western idea - an attic to store the chairs in until his youngsters were grown.

Unfortunately his knowledge of architectural priciples was limited - no one had ever told him that people who live in grass houses shouldn't stow thrones.
