Ah-ha you have caught the curse of the couplet!
I did try to warn you, once infected, you're stuck with it
I tried to prevent it as a matter of pride
I'm sure that I mentioned it - I even cried
They flow from my brain till it makes my head spin
So I try if its possible to make you all grin
But for chatting and banter
You can go at a canter
No need for deep thought
Or things of that sort
Just wing it and bring it
From some deep dark pit -
Its easy to go at one hell of a lick
I don't care any more if it makes you all sick
It occurs to me now like it did once before
It might be contagious or against the law
But I think I've been channeled by a couple of blokes
Two English gents that were clever with jokes
They conducted themselves with wit and elan
P'raps that's where my troubles, really began -
Oops!
I forgot in mid-flight to mention their names
The Two Ronnies - (I believe one has gone up in flames)

One good thing about music is that when it hits you, you feel no pain - Bob Marley
