Question: Why does Sideshow Bob not want to pursue Lisa since, if it hadn't been for her pointing out to Bart all the major flaws in the CCTV footage that would show that it couldn't have been Krusty (in Krusty Gets Busted), he wouldn't have been found out by Bart and Lisa? He knows Lisa is smarter than Bart, so surely he would have realised that Lisa was the brains behind the detective work that got him caught.
Question: Has any episode revealed what Marge's natural haircolor is? In the flashbacks in "The Way We Weren't", she is shown as a child with blue hair, and it turns brown when another girl burns it. However, I saw another episode where she walks past her mirror, notices a brown spot of hair showing, then picks up a can and sprays blue to cover it up.
