omz! This is brilliant! :D
At first glance, this sounds like it would be absolutely hilarious, but it relies on the assumption that your fundie friend is smart enough to understand and follow the rules of the game. Here’s how I’m fairly certain a conversation with the average fundie would go:
Non-Fundie: I’ll pick one source you can’t use, and you pick one source I can’t use.
Fundie: Deal! You can’t use Darwin.
Non-Fundie: Okay… You can’t use the Bible.
Fundie: I don’t need the Bible. It’s obvious that God created the world 6000 years ago.
Non-Fundie: Why would you say that? Radiometric dating, geological strata, and the fossil record, among other things, all indicate that the Earth is much older than that.
Fundie: I said you couldn’t use Darwin!
Non-Fundie: I didn’t. I can pull up published articles if you like.
Fundie: NO! If there’s evolution, it’s Darwin!
Non-Fundie: You do realize that Charles Darwin died more than a century ago, right? And that science has been done since then?
Fundie: Everyone knows that evolution was made up by Darwin! You can’t use it! You can’t explain anything without him!
Non-Fundie: *facepalm*
