Good Morning, Miss Bliss

The Boy Who Cried Rat (1x8)

:

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.
