Redditor terrafarma lives on a small farm, so my guess is that he is responsible for this sign. If you don’t get the joke, you might want to listen to the song. If you get the joke, you’ll love the comment flammablepenguins left underneath.
When the celery is in the Seventh House
And arugula aligns with Mars
Then spinach will guide the planets
And turnips will steer the stars
This is the dawning of the Age of Asparagus
The Age of Asparagus
Asparagus! Asparagus!
Pumpkin and understanding
Sorrell and tomato abounding
No more gherkins or derisions
Golden living dreams of onions
Mystic shallot revelation
And the leeks true liberation
Asparagus, Asparagus
When the celery is in the Seventh House
And arugula aligns with Mars
Then spinach will guide the planets
And turnips will steer the stars
This is the dawning of the Age of Asparagus
The Age of Asparagus
Asparagus! Asparagus!
Let the sun shine, Let the sun shine in, The sun shine in
Let the sun shine, Let the sun shine in, The sun shine in…
