Julia was Homer's manager after he became a famous opera singer.
She first saved Homer and Marge from an angry mob of fans before becoming Homer's manager. She tries to seduce him, but Homer refuses. Not accepting refusal, she tries to kill Homer, first with a Cobra placed in his cereal box, and later with a poisoned blowdart disguised as a conductors baton, during a showing of The Barber of Seville. However, both attempts were thwarted, first by Homer repeatedly whacking the cobra against the refrigerator door causing it to be dazed for the remainder of the morning, and the second when Homer stops her by hurling a French horn in the way, causing the dart to redirect back at her. However, the snipers actually saved her from poisoning by shooting her and then crashing the chandelier on her, squeezing out the remaining poison. While she is being sent to an insane asylum, she swears vengeance on Homer, but is abruptly cut off by Homer as he commands her silent and she obeys. She then realizes that she will never be worthy enough to get a man like Homer to which Homer agrees as she is shipped off the the insane asylum where she stays to this day.
