As a baker (intimate knowledge of butter wrappers) and a designer (intimate knowledge of printing technologies) I have yet to see sticks of butter with sides that perfectly flat, or wax paper that can be printed at what looks like about 600dpi with perfect color registration. This would have been so much color either without the insets, or if the insets looked like they'd been printed in one color with a coarse screen. Better yet, the heads would all be carved out of butter, since that's what the damn movie's about.
