“It’s been a while since I’ve had rug burns on my knees,
And my ejaculations formed a small Niagara;
Or the missus whispered: ‘Once more darling, please,’
As if she meant it.  Then along comes this ‘Viagra’.

“You see, I bought some, then I fell and broke my arm;
(It was the handrail round the bed I was erecting).
Well, you can bet the thought of sex has lost its charm.
Ten quid the lot.  I’m going back to stamp collecting.
