When an atheist is losing an argument with a Christian, the atheist will always accuse the Christian of joking or not being serious.
Christian: Stop dodging the question! We all know that, right down in your heart of hearts, all atheists secretly acknowledge Jesus as Lord and recognise that the Bible is 100% fact.
Atheist: I genuinely cannot believe that you just made such a f**king idiotic statement. Please tell me you're joking.
Christian: I call Tabor's Law on you! You know you can't defeat my arguments, so you're trying to claim I'm not being serious - the oldest trick in Satan's atheist handbook!
