'Abbott Elementary' has teachers laughing -- and relating

Though still in its first season, "Abbott Elementary" has captured the hearts of millions -- and even though some situations are exaggerated for laughs, real life teachers are nodding along.

The show, a new mockumentary comedy on ABC, follows a group of teachers at an underfunded elementary school in Philadelphia, who are just trying to make things work. Sure, the lights flicker. And the textbooks are so old, pictures of new presidents have to be taped in. And at one point, albeit briefly, the conspiracy theorist janitor steps in to teach.

And yet, the teachers, all in varying stages of their careers, persist.
