No matter how much we fight it, "um" and "like" are the most common words in today's English language. When you have a conversation with the first person you encounter today, keep track of how many times they say those two words because I guarantee they'll be 1/3 of the words of each sentence they speak. That's why I want to run a sociological experiment for the next week. I know it's going to be difficult, but for the next week, try and replace the words um and like with nachos and lotion. You never know, it might just change the world.
