An ode owed

Another day, another missive from Doctor Doorknob of Chichester. He didn't say whether he wrote this poem himself or found it elsewhere on the internet, but anyway here it is:

There was an old man, a bookbinder
Who went out with a friend on a blinder.
She invited him in
For a night of pure sin,
But I'm glad to record he declined 'er.

Thanks, Doc. Thanks too to LM and M for their great blog-comments: keep 'em rolling girls.
