Black Butler - I think it's a tie... :)---->>WRONG!!!! Sebby is just mimicking Ciel. As an emotionless demon, he only has feelings of greed, gluttony, selfishness, and lust and bunch of other bad things.

Digestive System: A 3rd grader's esophagus is about the size of a straw. Crumple up a small piece of paper and place it in one end of the straw (a clear straw is best for this). Model peristalsis by squeezing the straw to push the paper all the way down the straw.
