We all have that one favorite teacher, and Justin's sounds especially awesome. On a recent episode of "Real Change: Artists for Education," Justin told us about the special person at his school who inspired him to never give up. Mr. Monteith, Justin's former English teacher, would even encourage the budding star to bring his guitar to class and perform for his classmate. How cool is that? Check out the video: Wouldn't you love to have been a student in that class? Think of all the free private Bieber shows! Anyway -- do you have a favorite teacher? If so, who is it and why is he/she your favorite? We'd love to hear!
