It's late at night in the Bronx and a nun is making her way back to the convent when she is set upon by a couple of muggers in an alley. Just as they are about to have their wicked way with her, out of nowhere Superman appears and knocks seven colours of shit out of them. When he's done, the much relieved Sister says " Oh, Superman, I don't know how to thank you". To which the caped hero replies" It's okay - any friend of Batman is a friend of mine!" Right, that's enough Superman, I'll get me coat!
