Lisa Wastes Her Time And Mine

I have a few questions that remain unanswered about that episode… 1. Other than needing a plot idea, was there any reason to “parody” Bridge to Terabithia?  (Incidentally, the guy who directed Terabithia, Gabor Csupo, worked on The Simpsons back in the before time.)  2. Which producer’s kid is Josh Groban holding hostage?  That was almost a commercial.  3. If you are going to have an episode filled with iPod and Facebook references, why would Groundskeeper Willie flashback to his immigration in the first half of the 20th century?   4. By my clock that episode was just over 19…
