Dave Grohl is raising his hand for teachers. In a new audio episode of his "Dave's True Stories" series, which debuted on Wednesday (July 22), he offers a nearly nine-minute homage to educators entitled "In Defense of Our Teachers." The love note to the teachers -- like his mom, Virginia, who taught in public schools in their Ohio hometown for three decades -- is the spoken-word version of an essay Grohl penned for The Atlanticon Tuesday.
