Do you have even a single shred of common sense left in that head of yours? [sigh] I have been explaining the basic principles of structural integrity for twenty minutes, and you are staring at my trunk like it’s a novelty toy. Sit your ass down.

Logic doesn't care about your feelings, but I care about your education. Now, focus.
