Case In Point

I'm a breather mail receiver
Ad I don't know where I stand
Not since someone informed me that my house was built on sand
And it's not the earth beneath me
It's just the concept of the land
And I'm standing on the corner
When the buildings they all fell
If you blink once you're a goner
Everything just goes pell-mell
It's a real hard sell My conceptual hell
Not even good for kindling no
When the buildings they all fell
I'm a breather mail receiver
Bottom feeder just getting by
And you know it's all just part of the course
But you blame on some non-existent force
Oh yeah, of course you know you can't ride the concept of the horse
But still I try
In a carton desert landscape
With a pair o ACME jetskates
Focused on my destination
I seem to have forgot my station
Now it's time to face the nation
And I'm riding to meet you
On a brown gray speckled mare
But there's something that unnerves me
Thinking no one really cares
And I'm jumping over fences
On this obstacle course But it seems I'm getting nowhere
On the concept of the horse

I'm a breather
Bottom feeder
How many liters must I imbibe.
