Revealing mistake: In the scene where Jake fights in Cleveland, in one shot right before he punches you can see his opponent's mouthpiece is taped to his head so it will fall off making it look like it came out of his mouth. In the next shot he has his mouthpiece back in his mouth.

Joey LaMotta: Jack. Jack, don't start your shit. I mean it, don't start.
Trivia: The film was amusingly satired by Mad Magazine as Raging Bully - truly an apt title.
Chosen answer: No. But Jake's paranoia and possessiveness had consumed him to such a degree that he was convinced that he (Joey) had, based on Vickie's impulsive remarks.
