Those checksums there are reciprocal
What a shame, don't match the total
Bags and baskets full of files
In a container, locked in style

The question here is mathematics
Why don't files act like schematics
The only answer that could be
The files have changed a small degree

Which brings in you to find out why
The checksums don't add up and try
To nicely fit their new home quarters
And feel quite happy sounding laughter

Ever thought that files don't like
To be locked in - thus go on strike?
