The Crooked Line

It was a long and crooked line
And all the people in the line
Ended up with long and crooked necks
When they craned them to make those checks
That a person not in line
Should not end up front in line
For they were standing since so long
And it would have been all so wrong
If someone standing not in line
Should get ahead of them in line
While all they who their turns await
Already late, now get more late?
So all the people in the line
Stood in line and saw that the line
Was a line and remained so
Till they were done and free to go.
