When Craig decides to take a substitute music teacher job just to win over an ex, he ends up connecting with the students and the faculty.

Craig asks Jimmy to move in with the hope that he'll push the sloppy and jobless Ben to become a better roommate. Meanwhile, Ashleigh and Samir do some detective work to track down Supervisor Dalton's dog that Principal Taylor lost.

In the Season 1 finale, Craig looks forward to a Nasty Delicious summer tour, but soon considers ditching those plans, along with his brother, friends and students, when the band Earth, Wind and Fire present him with a tempting offer. Meanwhile, Samir feels guilty about seeing Ashleigh at her stripper job.
