You've got to remember the oracle bones. So I'm going to end it here, guys. We hope your brain is nice and big and bubbly. And I'm going to say it because I say it at the end of every video lecture because I know it's true with all my heart. Where tension goes, energy flows. We'll see you guys next time that you press my buttons. I want to give a huge shout out to our first hip-hues here, studentsofhistory.org.
