For an intro to a YouTube video trailer, these are the entire lines inspired by my gruff 8th grade math teacher after asking him an honest question. 

Seeking a male to read the teacher role, and possibly a young-sounding female although I could probably do it myself :)

M: Just do what I tell you!

F: Why?

M: There is no why. There's only Memorize The Formula!

F: I can't!

M: Then you FAIL!
