Baboon Rising - Pencil Eraser Aftertaste Lyrics

I've had an interesting experience
There was an odd taste in my mouth
My palate was some how stimulated
And only at a certain location
The taste of a pencil eraser
Location seems to be the answer
My theory is based on proximity
Of where the tower is relatively
If you draw a line
From point A to point B
The savoriness is defined
At least it is to me
This notion has been tested twice
I know it really should be more
But I can't help but take notice
That the tallest feed
mill might be involved
If you stop to really think about it
Why would I have such an aftertaste?
There's nothing I eat that would cause it
So, it's got to be that huge tower
