Love 'Em or Leash 'Em is part 1 of episode 17 overall and episode 4 of of season 2. It first aired on January 26, 2005
Jenny's got a new boyfriend, a rather cute boy robot named Kenny, YK-9. Despite having been made by Dr. Wakeman's rival, Dr. Mogg, Kenny seems to be the perfect match for the young teenage robot girl. But why is he scratching himself with his legs and howling at the moon? And what happens when Sheldon gets jealous?
Mrs. Wakeman (to Jenny): XJ-9! You disobeyed a direct order and went out with that, that, ANIMAL! Maybe, I should've followed Mogg's pathetic modifications and made you part dog!
- Sheldon has a cat outfit that he claimed he wouldn't wear outside of the Feline Fan Convention, establishing that he is a cat lover. He wore the outfit to expose Kenny as part dog (causing Kenny to chase him), and later to "serenade" Jenny by meowing on her backyard fence at night.
- The episode's title is a pun of "Love 'Em or Leave 'Em".
- In this episode, Jenny has a nightmare about Kenny. But, as we learned, in 'Daydream Believer', Jenny, as a robot, isn't able to have dreams. She has another nightmare in Mama Drama.
