Rhino???? (NaPoMo 18)

Form: Epistle Sonnet 18 – aba adecb cdcd ee
Form: Love Subject: Rhino

To take my thinking out of double-dutch
Removing that elephant from the room
For my insanity has lost its touch
The moth-eaten rhino’s talking too much
(Well, I had to work it in somehow, right? –
I dare myself not to take that bit out) –
This challenge I am beginning to regret
But I won’t give in to the doom and gloom
Elephants and rhinos, I never met
Any, not one, that would not stand and fight
In fact they have offered me this here bet
So for my love of words I have to write
Nonsense in a sonnet I’m almost out
A last line to bring a new one about
