The mating song of junk crabs

Do you hear this noise, dear?
I'm getting annoyed here
Junkcrabs settle in our clock
they racket about as if to mock

This noise is past-bearing
If I am not erring
junkcrabs in the chronograph
are having a laugh

clickedy-clickedy-clickedy-click
clickedy-clickedy-clickedy-click
clickedy-clickedy-clickedy-clickedy
bla bla bla

I'm shaken awake and
If I'm not mistaken
Junkcrabs nesting in our clock
they racked about in the tickedy-tock

clickedy-clickedy-clickedy-click
clickedy-clickedy-clickedy-click
clickedy-clickedy-clickedy-click
clickedy-clickedy-rattle-groan-tickedy
creak-helter-skelter-gargle-zizzle-zoom
p'tang-rumble-grumble-bazinga-kaboom
oopsiedaisy-clatter-outch-gurgle-argh

All doubts excluded
if I'm not deluded
pincered agitators
rummage our chronometer

It's late and I'm tired
If I'm not ill-wired
junkcrabs cause that dreadful noise
in our time measurement device

What's that now You kidding
trumpets and fiddling
what the [bad word] I'm going to snap
thin ice — risk of skidding

How can you sleep
with junkcrabs near the ear well to my sorrow
I fear my dear we have to x
our wedding tomorrow
