In today’s special episode, Mango sits down with Erin McCarthy, editor-in-chief of Mental Floss to talk about everything Teddy Roosevelt… from whether he really climbed a mountain out of spite, to how a seal inspired his fossil collection, to what made him so darn productive (hint: it helps to drink coffee from a mug the size of a bathtub). Plus, we get into just how high-pitched TR’s voice was, and why Dr. Seuss was so darn scared of him.
