Every Thursday in geology merit badge, Matt Grob would make the kids watch the Futurama Episode where Planet Express finds Fry’s dog as a doggy non-fossil.

Recently, I’ve gone back through the xkcd.com comics archive and done mouse-overs to view the title parameters of images that usually have secondary jokes in them.
