From Automated Alice by Jeff
Noon:
"Alice! You must know what I mean!" Celia cried. "A horseless carriage
is what the people of the future call a carriage that isn't being pulled
by a horse."
"Is that similar to a pianoless lampshade?" asked Alice.
"Whatever's a pianoless lampshade?" asked Celia.
"Why, it's a lampshade that isn't being played by a piano, of course."
