The tick of a clock fills the room

Is that something it's supposed to do

The smallest tick

The smallest tock 

The tick of a clock poisons your mind

It sounds like its coming from behind 

The smallest tick 

The smallest tock 

The tick of a clock makes you quake 

When you think too much about what it takes

It takes

The smallest tick 

And the smallest tock

For a moment to pass and the clock to stop.
