I am also intrigued by the strange package, but, word of warning, if it turns out to be the BMF, let XH find out other than from you. Remember the old saying "Don't kill the messenger". It could backfire.
On the other hand, IF it does turn out to the be BMF, which I find VERY strange. Perhaps you could return the favor by anonymously sending him the book "Dealing with Latent Homosexuality" LOL
