This one is an unabashed homage to the devil's lettuce.
Lyrics
The name of the game, the pipe dream plans,
the name of the strain, Cardigan Dan.
Mark, I'm on my way over
to try your four leaf clover.
For you it's just a past-time,
for me it's just a life-line.
It evens out afternoons,
it evens out the mind blues.
