"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,
You homework comes out, quick and clean as can be.
Here it is – “nine plus four?” and the answer is “three”. Three?
I guess it’s not as perfect
As I thought it would be.
