I guess I'm more susceptible to product placement than I thought. While watching the 4th season of Fringe I noticed a statute of what looked to be a figure from the chart of Human Evolution of Man. I though wow that's such a cool idea. So I searched all over the internet using words like evolution, caveman, Homosapien, Homo Erectus, and then Neanderthal—and pop—Neanderthal Eraser!! Now I'm not sure this is the same product used in Fringe episode 2 "One Night In October", but I think it's still a cool idea for an eraser.
