It ain't no pot o' gold, it's where the product sold
It's where we lock and load, and and cop that rock then roll
from Talib Kweli – Gutter Rainbows Lyrics on Rap Genius
Meaning
There’s no pot of gold over that rainbow, son.

There certainly is pot being sold there though, and not by a leprechaun… More like guns are being fired and cops are harassing in this fairy tale.
