I've never gotten such spam....ever...
maybe you give your email to some discussion about Religion, but again I spybot most spammers and popups and worms and Yahoo did the bulk mail thing for me. By any chance, is your account that got such spam a hotmail account?
Hotmail is the worst...
Name on the account matters for the spammer, something to do with any religious symbols.
Fish could be religious, so does lamb, zen, en(light)en, moon and star, sid(harta), dal(ai lama), khan,
jc murphy... tee hee...
