NBC has ordered an untitled sitcom from former “Saturday Night Live” writers Seth Meyers and Mike O’Brien to pilot, the network announced Monday. The single-cam comedy, formerly titled “AP Bio,” follows a hilariously cynical Ivy League professor who loses out on his dream job and goes to work as a high school biology teacher where he imposes his unorthodox teaching style and uses the kids to plot out revenge on those who wronged him.
