Writer Joss Whedon and director Drew Goddard created over 60 different types of monsters were created specifically for The Cabin in the Woods including Sugarplum Fairy, Reptilius, Angry Molesting Tree, Fornicus, Wraiths and, of course, a Merman. That’s just one of the many facts packed into the latest episode of You Think You Know Movies, which catches up with The Cabin in the Woods.

The telescoping coffee mug/bong was actually fully functional as both a coffee mug and a bong. It was actually a specially made prototype that cost the production $5,000. Of course, it didn’t take a bunch of stoners very long to try and replicate this. Shortly after the movie opened in theaters, actual coffee mug/bongs went up for sale on the internet for $50. Just remember, it’s for smoking tobacco only (*cough*).
