The Homework Machine
by Shel Silverstein

The Homework Machine,
Oh, the Homework Machine,
Most perfect
contraption that's ever been seen.
Just put in your homework, then drop in a dime,
Snap on the switch, and in ten seconds' time,
Your homework comes out, quick and clean as can be.
Here it is— 'nine plus four?' and the answer is 'three.'
Three?
Oh me . . .
I guess it's not as perfect
As I thought it would be.
