    How do we know which way is up? For example, how do we know Australia is at the bottom of the earth and not the top?

    Do we still submit questions [email protected]? Or just here in the comments? They didn't say anything in this video so i'll just leave my submission here I guess. 


    This is both kind of a science and philosophical question. Do animals in captivity understand that they're in captivity? I'm especially interested in the apes who can learn sign language because if one were to sign to their trainer "I want to be free" do we have a moral obligation to free them?

    This episode has the nerdist dirty talk ever. Also if you want to see an extreme case of dental decay in animals look up "Squirrel McNastyface" on youtube.

    Are all of these episodes pre-recorded before she changed her hair? Or did she come back after and filmed more?

    Something about Chris just compels you to wrap a blanket around him and feed him hot chocolate. Nobody tell him that Santa isn't real.
