In just two short 13-episode seasons, the NBC comedy series A.P. Bio was already showing promising signs of evolution. The series started out focusing on disgraced Harvard philosophy professor Jack Griffin (Glenn Howerton), who missed out on his dream job and was forced to return to his hometown of Toledo, Ohio and work as an advanced placement biology high school teacher. But instead of teaching his gifted, oddball students, he uses them to get revenge on the rival who took his job.
