In the same episode, usual service resumes for the murderous Bob when he gains control of the remote for his ankle bracelet and steals into Bart's bedroom at night with a large knife. Upon realising that he can't go through with the crime however, after it dawns on him that he has "grown accustomed to Bart's face", Bob instead jumps in to a musical parody of "I've Grown Accustomed to Her Face" from the 1956 musical 'My Fair Lady'. "I've grown accustomed to his face and dreams of gouging out his eyes I've grown accustomed to my hate my plans to lacerate To disembowel to hear him howl The very reason that I live is plotting how to watch him die I know this chubby scalawag has made my life a living hell Surely if I drank his blood, I'd be at peace but well..." Bart: "You've grown accustomed to my face" Sideshow Bob: "This isn't a duet" Bart: "Sorry" Sideshow Bob: "I've grown accustomed to your fear Accustomed to revenge Accustomed to your face." Another wonderful Bob/Bart moment that nicely wrapped up one of my personal favourite Simpsons episodes.
