Sense Sonnet - Tickler

Coal Toll

For want of an "0" the coal came,
And bit the trader on his butt,
Giving the jerk unwanted fame,
As his trade's perfect storm did cut.
Computers like their "0"s and "1"s
To give them reason to compute.
Data put in them hits and runs
According to programmed pursuit.
To err is human, not machine.
One day this human trader will
Be unemployed, still cocky mean,
Replaced by circuits sure and still.

Of the "1"s and "0"s of this trade,
It was 1 big 0 that was laid.
