Please! Do include your religion on your CV!
If you think it is that important, that big a part of your life, please, by all means, do include your religion, and all your religious activities on your CV!

I am currently consulting for a California-based Fortune 150 which is looking for a new senior SysAdmin, reporting directly to the CTO.

 Yes, it does make your CV stand out ... and say "shred me, oh, please, shred ME! Can I please, pretty please, be the first into the shredder?". (Yes, there are three s in there ... )
No, I am NOT likely to be bribed into hiring you with a photograph of your kitty, and frankly, I don't really care what YOU look like, either; this is a technical position, not a beauty contest.

Likewise all you idiots who sent in CVs and resumes on Thanksgiving themed paper ...
 Just paste the text into the body of the email, you nit-wits! I'll probably reject it anyway, because we specified FAX, snail mail, or online-form applications only, but at least you'll save a little bandwidth!
