The Darkest of the Hillside Thickets - the Math Song

I could really have picked almost any of their songs as as well, they’re kind of coloured (greenly) by that the group started out as a Call of Cthulhu roleplaying group. But I picked this one because it’s a damn catchy stoner punk song.

Y
Y equals X over 5
5 to the power of psi
psi is the square root of 3
3 is the number for me
I said

X
X by the tangent of N
N minus pi over 10
That equals negative 9
Negative 9 is so fine

You’ve got a brain
And nobody really needs another love song
Love song
(x4)

N
N is the product of v
V and the cosine of 3
Cube that and add 44
And not an integer more
Baby

V
V equals 1 through the sum
The sum of 101
And 83 over 5
What is the value of Y?

You’ve got a brain
And nobody really needs another love song
Love song
(x7)

You’ve got a brain
Yeah I heard you’ve got it

Bonus song from the past: Mekons - Hey Susan. Because retelling a thick book in under three minutes while at the same time have fun with a Beatles’ song title is to me pretty geeky.
