The good doctor says, hey, come on, some extra credit. How did you come up with this idea? How did -- well, I was sitting in my bed actually after a football game. But I was listening to xo tour life and I remember that she had asigned an extra credit assignment where I could make a music video out of anything and all my cells are dead just kept repeating in my head and so I scrambled to check my notes to make sure it had something to do with biology and I started writing lyrics that were parallel to the song so I could remember it better and called up a few teammates and made a video and it just blew up from there. Professor, what did you think when you first heard about this? I can't hear. Sorry, what did you think when you first heard about the video? Professor Davenport? Oh, when I first heard about the video, I actually heard about it before I even checked my e-mail to see that he turned it in and I received a text message with a link and so I clicked on it and I was like, oh, this is catchy. Okay, this is nice. This is nice and I saw all the likes and all the retweets and I was like, wait, this is my student. Wait a minute, this is Julien. Oh, my goodness. Okay, okay, so it was -- I was so excited but I mean, I didn't expect anything less. He is an excellent student. Already doing well in the class, minus extra credit. He's an anti-athlete. He's on the football team. He's amazing so -- again, I did not expect that. Love that. But, professor, professor, you didn't answer the big question. Did he get the extra credit? Of course, he got the extra credit. It's time to share. Let's hear some more. Come on, Julien. Say what. Let's hear some more. You ready to rap. Oh, yeah. You guys want to sing with us? Sure.
