I went to a play recently. Immediately after the intermission, some cast members sang this short (and terribly written) song:
This treatise we sing on this section of stage
is not so long as to discourage.
It'll draw all your effort out, lessen your boredom:
you'll be like a farm machine, gaining momentum.
In summary, this isn't over-hard;
your pains of labor'll yield tempting reward.
I spend the second half of the play trying to figure it out and missed the action, and I still haven't got it. Can you figure it out?
Hint (added later):
