While Joey (David Coulier) goes to the dentist, Jesse (John Stamos) accompanies Michelle (played by the Olsen twins) to her preschool class. Unfortunately, what started out as a nice day quickly turns sour when, after fellow student Aaron (Miko Hughes) pinches Michelle, Jesse clashes with the teacher (Roseanne Katon) over how to handle the crisis. Meanwhile, DJ (Candace Cameron) and her pal Kimmy conspire to "help" Steph (Jodie Sweetin) by rewriting her horoscope. ~ Hal Erickson, Rovi
