There's a book in Australia called Australian Comic Verse that has poems by Pixie O'Harris (somebody told me she was Rolf Harris' mother but I don't know if that's true. The one that springs to mind, and this was the complete poem, was
I saw Chaucer
In a flying saucer
that's worse than Rolf's
Whatever I did they said was false
They said, "Quick march!" I did a quick waltz
(Jake the Peg)
