 The agnostic but half-Jewish Sam begins wearing a yarmulke to work to cover his bald spot. But when he starts taking off esoteric Jewish holidays, Clark becomes annoyed. The ultra-WASPy Clark starts a Jewish conversion class at the firm so that he and his gentile colleagues may also avail themselves of Jewish holidays. For Sam, this means war. Stu attempts to flirt with Robin, thinking he has sprayed himself with a can of synthetic pheromones (given to him by Sam and Clark). But the spray-can is actually filled with a scent that activates the robotic mail trolley, and Stu spends the duration of the episode being incessantly followed by the electronic cart.
