Caution: No humans were injured in the making of this podcast. This is a very challenging passage. It's designed to make you stop dead in your tracks. It was very successful.
What did He just say ?  Tear what out ?  Saw what off ?  Throw who in a furnace ?
What was Jesus really trying to get at?  The clues to this confusing passage are hidden in context of ancient Jewish Rabbinical Teaching. 

“If your right eye causes you to sin, tear it out and throw it away. For it is better that you lose one of your members than that your whole body be thrown into hell. And if your right hand causes you to sin, cut it off and throw it away. For it is better that you lose one of your members than that your whole body go into hell.”

Matthew5:29-30ESV
