Please go on.

Please go on I’m asking kindly.
Official parts should fit precisely.
With special grease you should slide in lightly.
If only you would push on quietly.

This is not a job that’s going politely.
In videos they fit in nicely.
I’m not sure it’s filmed precisely.
As fitting this looks quite unlikely.

Enough is enough I shout profusely.
Waving my hammer with all my mighty.
And as I strike it shatters badly.
It seems to me this part is faulty.
