Bitter Clingerzz

Why don't we say it 'fingerrz'
Like other words like that?
The greasy glottal
On the g
When others like it lay flat?
Like they got taken to
By some alphabat
Swinging ringer
Some bitter clinger
With an appetite for claptrap?

Someone sort it
Bring us fields of level
Play
Replace the rover with a winger
Like all the singing
Sounds the same
Like there’s a demon
Ringing
Bells inside your skull
Till you're insane
Bitter ringing in your brain

The time is ripe
Hark the harbingeerrrrz
All good fellowzz
Do not linggeerrz
While you're at it
Imprison all the chingerrrz do
Or pretty soon there’ll be nothing left to cling to
For all you
Bitter clingerzz

Marry principal
Lower your ring upon its fingeerrz
There it is!
Now clench and pray
It doesn’t make a fist
Oh the shrieking in the mist
Of Pestilential Mire bringerrrz
Presidential plague slingerzz
Bitter clingerzz
Bitter clingerzz
Bitter clingerzz

Why don't we say it finggeerrzz
Like other words like that?
The greasy glottal
On the g
When others like it lay flat?
Cos it's a finger and it's permanently raised
Are you so dumb you confused it for a thumb?
