My Childhood Was a Lie

When you were a snapper, I bet you had a picture book of dinosaurs. You did, didn't you? Alright then, pop quiz: what was the largest land dinosaur? See, you're thinking to yourself that I'm trying to trick you into thinking T-Rex, but you're clever and instead thought Brontosaurus. Hooray for you. But guess what? There was never any such thing. Sucka.
