Jesus' severe teaching in the 9th chapter of Mark's gospel is a good example of radical exaggeration to make an important point. Jesus isn't mandating the cutting off of feet, chopping off of hands, or the actual plucking out of eyes. He IS mandating that we take a hard look at our own fundamental sins and excise them from our lives. Arrogance, lying, and lack of forgiveness, these are the "big ones" and the most challenging to be free of.
