Be she tramp, pixie, or even a chap,
Whatever the reason, beware of the clap.
For bush pushing suits one better if he,
Can avoid such plights as the firey pee.

--why, you should ask, would a maiden stand there?
If her reasons I knew, t'would only be fair
That I told you, but I know of just three
Types of maiden to abound in the trees.

It is all in Billys fertile if frustrated, imagination...
