We're taking a short dirt nap this week in preparation for October's frightening festivities! Enjoy this classic, slightly spooky episode and join us next week as we kick off Monster Month!

It'll be worth the wait, I promise!

Follow us on Twitter @SciShowTangents, where we’ll tweet out topics for upcoming episodes and you can ask the science couch questions!
