Mr Greg's knee is clunky broken, but a specialist has spoken
He says he's gonna mend it, but first he'll have to bend it!

He's going to hack it open, his knife he'll have to sharpen
Squirt it full of lotion, and give Greg caps full of a magic potion
The lotion will stop it creaking, the potion should prevent it squeaking

Within a few short weeks Mr Greg should have two nice knees
Which will allow him, once again, to out-run the police!

The operation might go wrong, and he'll end up worse than before
He might have to ascend the stairs towards that disability floor
He might have to live a life of leisure, chilling-out forever more

A fact he's sure not to like, is that he won't be able to ride his bike
He might be forced to finally get a moped or the like
And suffer the insurance premium and fuel price spike!

The specialist should mend it, these things rarely go wrong
Then Mr Greg can sing the "I've got a flexi new knee joint" song!
