The two clashed several times on last weekend's Celebrity Apprentice episode, first when Lampanelli called the actor "f**king useless" and later in the boardroom when Ferrigno said he'd throw her through a wall if she weren't a woman.
When Team Forte were revealed to have lost their task, Lampanelli and teammate Dayana Mendoza successfully convinced Donald Trump to fire Ferrigno.
The Incredible Hulk star has now admitted that his hostility towards Lampanelli has only grown since his firing.
"I wish I could've put her in a sleeper hold," Ferrigno joked to TV Guide.
Ferrigno - who suffers from a hearing impairment - went on to suggest that Lampanelli has only managed to survive several losses because she intimidates her teammates.
"Most people are afraid of her and I'm not," he insisted. "She stepped over the line, especially after all I've overcome."
The Celebrity Apprentice continues this weekend at 9/8c on NBC.
