"Kick the Habit" is the 6th episode of Season 1 of Kick Buttowski: Suburban Daredevil.
Facing the risk of being sent to military school because of his stunts growing out of control, Kick sets out to prove to his concerned parents (and the neighborhood) that he can refrain from performing any stunts for an entire day. Kick ends up struggling, so Gunther tries to help him by keeping him inside a plastic ball and strapping a machine to him that shocks him. But nothing works when Brad keeps tempting him with stunting opportunities. This leads Kick and Gunther to get advice from Wade to relax. Kick is then able to resist all of the neighbors' attempts to inspire Kick to do stunts. That is, until Brad shows him an awesome personal truck carrier (the same one belonging to the colonel who runs the military school that the neighborhood wants Kick to be sent to). He throws Kick inside where he's given the opportunity to drive it. With one minute left, the truck takes off and Gunther fears Kick will be sent away, only for the smoke to clear and reveal that Kick wasn't inside. Kick ends up staying while Brad ends up getting punished for stealing the truck.
Gunther is shown in his closet, smelling his fingers.
