The Best Lines

Just wanted to share a random thought--something to kick around in your head when you have nothing better to do.  A fellow author mentioned a topic to me that was discussed in one of her writer's groups:  Who has the best lines?  Is it your protagonist?  It should be.  He/she should always have the best lines.  But many times, people tend to "give them away" to a witty side kick or villain.  So who has the best lines in your story?  It's certainly something I'm going to think about as my character continues to lead me down his path of growth.
