Dewey Finn: 8:15 to 10, rock history. 10 to 11, rock appreciation in theory. And then band practice till the end of the day.
Frankie: What about math?
Dewey Finn: No, not important.
Jack Black and Angelo Massagli in the feel-good film School of Rock (2003), which tells of a rock musician who gets his life back on track by inspiring a group of young students in a prestigious prep school.

Loved this movie
It’s so feel-good. And important messages too (though not for maths teachers haha)
I guess you need to put what’s important in life first. Fortunately, it is not math.
Ha! I’m a big fan of Jack Black. He just has such warmth, energy and sincerity.
One of my all time favorite feel good movies.
It really is. How cool would that class be to take?!
