My favorite video is definitely
Morgan Freeman's. While it doesn't explain the program too much, it's a good video and we found that it can make the program very attractive in people's first impressions. We showed it in our recruitment presentation after 2012's season and got 80 people signing up, out of about 150 people who watched the presentation (almost all of the Freshman grade at the time, we managed to get the school to make it a mandatory presentation for Freshmen), and in our team isn't exactly the most popular program of the school.
