Eh, you don't have to say pity too many times before it stops sounding like a word. Pity. Pity. Pit- See? That is only like two times and it's already just gobbledygook. Gobbledygook, too. I can't- I can't even get through that once. Gobbledy- Now see, I am not even consider the last syllable and it's already... [sighs] Great. Now, I am forgetting what I was talking about... Which is another reason to pity me! YEAH! Back on topic, baby!
