Where is the cuckoo?

the pendulum sways
one weight rises
the other falls
but where is the cuckoo?

the hands slowly move
the hours come
and the hours go
but where is the cuckoo?

one thought makes me frightened
another turns my stomach
I pull my hair
but where is the cuckoo?

crawl out of my bed
turn on the light
go to the mirror
the damned cuckoo stares back at me
