Thinking of Shrubberies In Honor of Earth Day

The Knights
Who 'Til Recently
Said Ni, oh keepers of gibberish
and antlers, and deep love
of leafy things, demand a sacrifice
of the utmost foliaged proportions
before you shall pass, you must
visit Roger, he who maketh shrubberies
alas is called The Shrubber
and he shall bestow upon you
a shrubbery that's quite nice, but
TKWTRSN will be only somewhat
satisfied, they will demand
a second shrubbery, one slightly higher
so you get a two-level effect
with a path down the middle
and if that wasn't enough to appease them
they will try to demand that you cut down
the mightiest tree in the forest with
a herring
but all you ever had to do was say...
it.
