The fishing metaphor strikes me as especially harsh, right from the start, with no imagination required. The shepherding metaphor becomes so only when you think about it closely and follow the image to the very end.
Pink Floyd exploits the pastoral imagery of Psalm 23 in "Sheep":
What do you get for pretending the danger's not real?
Meek and obedient you follow the leader down well trodden corridors into the valley of steel.
What a surprise! The look of terminal shock in your eyes.
Now things are really what they seem.
No, this is no bad dream.
The Lord is my shepherd, I shall not want.
He makes me down to lie.
Through pastures green He leadeth me the silent waters by.
With bright knives he releaseth my soul.
He maketh me to hang on hooks in high places.
He converteth me to lamb cutlets.
For lo, He hath great power, and great hunger.
When cometh the day we lowly ones,
Through quiet reflection and great dedication,
Master the art of karate,
Lo, we shall rise up,
And then we'll make the bugger's eyes water.
