According to the Christian religion, everyone who is born is born with original sin. What exactly does that mean? If you can't come up with an original sin, you won't be allowed to be born?"
To make sure you come here with original sin, there's a guardian on the other side who checks out the sins of those souls who want to be born.
"Original sin? Ok, that's a good one. You can go." "Yo, you! Let's see what you got? That's pretty original alright. Move on!" "Sorry, can't let you pass. That's been done before. Come back when you come up with something new."
