Did God Really Say That?

In future videos I'd like to take a Bible verse or passage that has been misinterpreted, and show through a short inductive bible study demo what God is actually saying there. For example, Mark 16:15- "They shall take up serpents; and if they drink any deadly thing, it shall not hurt them"... meaning that Christians should drink poison and hold rattlesnakes to demonstrate God's power. Did God really say that?
What are some other topics we should take a look at?
