Help me rid the world of "You know," "Like" and "umm"

There is something that drives me crazy besides trying to figure out why the "Kardashian" women are famous. It's when people incessantly use the fillers, "You know," "Like" and "Umm" while conversing. Umm, like, you know what I'm talking about? You never see people include these words on paper(unless being quoted)so how come they are spoken nonetheless? Because these words are now part of our vocabulary, our culture. We hear everyone else around us using them and so sub-consciously we use them too. And it's only when someone else points out to YOU that you are doing it that you realize it. One afternoon I was sitting in my favorite coffee shop, the one that starts in S and ends in S when I happened to over hear a conversation between a smartly dressed older man and a young woman. They sat right behind me so eavesdropping was unavoidable. After noticing a few "You knows" coming from the young woman who was obviously a college student I started to count them. Sometimes I couldn't count them fast enough which made me laugh, but not loud enough to draw attention to myself. After twenty minutes I had to leave the coffee shop to run an errand but not before counting 157 "You knows" before leaving. I left them there still talking, racking up even more YK's after I left. So what are we to do? You may read this and think me a snobbish intellectual, but I, like others had fallen into the same trap myself. It takes a constant awareness of monitoring my own speech to not utter some YK's. Yet I still slip. Is this a problem on the scale of global warming? No, but habitually using these fillers slows a conversation down, slowly grates on the others involved in the conversation and ultimately makes the user look un-intelligent. The words "You know" and "Like" cannot be stricken from the English language. They still have meaning in the proper context. For example:Do YOU KNOW the way to San Jose'? I would LIKE to take you to bed. There really is no logical need for "Umm" You know?
