Young girls are cheap today...
This finance-on.net article reminds me of the following fine piece of doggerel verse:
Young girls are cheap today,
Cheaper than yesterday,
You get one for a shilling,
One and six for one who's willing,
Pretty girls are a shilling more,
That's two and sixpence for a whore,
Young girls are cheap, cheaper today.
Yet another proof that Life imitates Art!
For the rest of the poem, see this web site, which contains a wonderful treasury of bawdy poems.
P.S. Now that I think about it, another good thing about the poem quoted above
is that it gives you an opportunity to practice thinking in terms of
British pre-decimal currency...
