I like to chat with Jehovah's Witnesses,
partly because they're nice people, and partly because I love demolishing dreadful reasoning, which the ones I've interacted with are really good at.
One particularly delicious example I've not had the opportunity to bring up with them is this:
A Watchtower magazine they handed to me once had an interesting article on whether or not God could see the future. In fact, they had trawled through the Bible and come up with some pretty compelling reasons (the Bible's authenticity taken as read, of course) for the decision that God could, in fact, not see the future. According to the Bible, they explained, God can't see the future. The future dances mockingly outside his grasp just like it does with all of us mortals.

The next issue I received based an entire article on God's plan and took it as read that he can see the future.

You'd think he would have seen this coming and given them a hint, but this could be one of those "mysterious ways" dealies.

You may believe you have demolished their arguments
But actually they are looking down on you as a an unenlightened fool who hasn't yet "got it".

The JWs I have met have a faith that is as absolute as their all-knowing smugness. There's no way you can turn them using science and reason. If you argue a point you believe to be oxymoronic or contradictory, they will close their eyes in divine bliss and tell you that such beautiful puzzles are part of the joy of God's creation and you, you poor, confused, questioning, angry soul - you can never know the mind of God.

It's better if you just shoot them, really.

Well...
Did you pull them both out and ask for an explanation? I love those magazines, they're hilarious. All they need is a Jack Chick comic at the back and they'd be as funny as Mad Magazine.
