I mean to say, I know perfectly well that I've got, roughly speaking, half the amount of brain a normal bloke ought to possess. And when a girl comes along who has about twice the regular allowance, she too often makes a bee line for me with the love light in her eyes. I don't know how to account for it, but it is so.It may be Nature's provision for maintaining the balance of the species, sir.
