Zack and Nicki are in the middle of an argument when Miss Bliss assigns them to work on a project together--to convince people to buy a telephone as though it were a new invention. They do not want to cooperate with each other. Nicki is insistent that they do it her way so Zack backs off and lets her do it her way.
Zack's father promises him a ski trip if he can get a B on his history midterm. He's studying, but he knows he won't be able to do it so he comes up with a plan to release Screech's pet rats in the school so that the school will have to close for a few days. The test will be postponed and he will have more time to study.
Screech's friends encourage him to stand up to bully Deke Simmons
Good Morning, Miss Bliss is an American teen sitcom that aired on the Disney Channel from 1988 to 1989, starring Hayley Mills as a teacher at John F. Kennedy Junior High School in Indianapolis, Indiana. The show was originally a pilot for NBC, which was inspired by NBC president Brandon Tartikoff's idea for a show about an "inspiring" teacher. NBC decided not to pick up the pilot, but Disney Channel did, premiering the show on November 30, 1988, and airing it for one season. The show was later retooled as Saved by the Bell, with much of the same cast but without Mills, and with a different setting. The latter show focused on the students rather than the teacher, and had a much more successful run.
