They have to fill up space. You know, I understand. They are trying to be entertaining."They are trying to fill up space everyday and sometimes they don't have anything interesting to talk about so they got to make s**t up. I understand, I read some of the blogs sometimes, and I think it's funny. You can't let that get to you, you just got to keep living your life."
