At least the first part of ‘Every sperm is Sacred’ is quite nice, you could almost use it as some profession of your religion:
'There are Jews in the world,
there are Buddhists
There are Hindus,
and Mormons,
and then
There are those that follow Mohammed; BUT
I’ve never been one of them.
I’m a Roman Catholic
And have been since before I was born
And the one thing they say about Catholics is
They’ll take you as soon as you’re warm
You don’t have to be a six footer
You don’t have to have a great brain
You don’t have to have any clothes on
You’re a Catholic the moment Dad came…’
We should just change the lyrics a bit and we’ll have some nice Profession of the Catholic Faith. Follow it up with the Nicene Creed afterwards.
