Glasses Geometry Must Incorporate Pi

 My darling husband has two sets of glasses.  One set has round lenses, which he wears for everyday use.  The other set has rectangle lenses, with sturdy frames for work.

Today, wearing his sturdy work lenses on his way to the shower after work, DH heard Sparkle say, "Annoying rectangles, get back to circles." When he put on his regular glasses, all became well in her world.
