Under the influence of new girlfriend Stacy (Kari Michaelson), easygoing Joey (David Coulier) vows never again to let himself be bossed around by Jesse (John Stamos). Unfortunately, Joey's new-found assertiveness comes at precisely the wrong time as far as Jesse is concerned, causing a serious rift between the two. Meanwhile, amateur physicians DJ (Candace Cameron) and Michelle (played by the Olsen twins) perform emergency "surgery" when Steph's beloved teddy bear is torn asunder by family dog Comet. ~ Hal Erickson, Rovi
