I Stibbed My Fungers!

Look at my fungers! They’re all big and bruised!
I am so confused and utterly bemused.

I stibbed them, oh I stibbed them good!
Now they crack when I don’t think they should.

They’re black and blue like an old man’s shoe.
When I bend them they sound like a broken kazoo!

Let this be a lesson to all of you youngers.
Be careful! Be careful what you do with your fungers.
