My history teacher in high school chronically said "Okay?" at the end of almost every sentence and "Um" through-out each one....I was bored enough to calculate it out one day, it was 2.4 ums per minute and 1.8 okays. An hour of that every week day was enough to train me to watch my speech patterns. Then there's like those people who like, say like after every other word, because everything's like something else, not like what it really is...like right?
