So I don’t talk about this part of my life so much on here, but I did Speech and Debate (formerly: Forensics).
The video is Josh Gad (aka: Olaf from Frozen) doing what is called OO, or Original Oratory. Without getting into the nitty gritty of it, is basically a 10 minute original speech that explains and serves a concept of the authors own choosing. To this day it is my favorite thing he has ever done.
This is the best I have ever seen, and he rightly won the National Championship that year. He also won the year before that with this speech.
