My favourite no brainers;
I was arguing with a convinced Catholic on another forum once. He asserted that the other planets orbited the earth. He claimed that without a fixed third point of reference it was impossible to disprove him.
I pointed out that the distance of those planets from the earth was not constant, and indeed not constant in exactly the way we would expect if all of them - including the earth - was orbiting another body that occupied the exact position that the Sun happens to be in.
I didn't get a response.
We moved on to evolution, and I invited him to visit the Smithsonian to review the mountain of evidence. His reply was "what evidence?".
What are your personal classics?

I must not be nasty. I must not be nasty. I must not be nasty. I must not be nasty. I must not be nasty. I must not be nasty. I must not be nasty. I must not be nasty.
