S4, E4: When Brick develops yet another quirky tic that begins to overshadow his whispering, Frankie and Mike are urged by the school therapist, Dr. Fulton (guest star DAVE FOLEY), to get him a small pet so that he can learn to bond with it, which in turn will help him bond with people. But when they present Brick with an ill-tempered bunny, the tiny animal teaches the Heck family the true meaning of evil. Meanwhile, as the Homecoming dance approaches, Axl finds himself dating cheerleaders Courtney and Debbie (guest stars BRITTANY ROSS and NATALIE LANDER) – but he doesn't know which one of them is actually his girlfriend; and Sue tries out for school mascot.
