Farrah Abraham's temper flared throughout the entire season two of MTV's hit reality TV series "Teen Mom OG," and not even her mother Debra Danielsen or her father Michael Abraham were spared from her sharp tongue. In a sneak peek for the Monday night two-hour season finale, Abraham takes her frustration out on her producer Larry Musnik and even goes as far as insulting him on camera.

Abraham and her production team, which includes Musnik and producer Heather Walsh, get involved in a heated discussion when the "Teen Mom OG" camera crew shows up at Abraham's Texas home. She refuses to film with the crew because of an issue in her contract with MTV. Abraham signed up to star on another reality TV show with her mother, which Musnik declared is a conflict of interest because it's too similar to "Teen Mom." After Walsh knocks on Abraham's door, Abraham asks to speak to Musnik directly.

"Hi Larry Barry," she says sweetly. "I don't know why anyone's here today because there's really a void in our agreement because you wouldn't allow me to seek other forms of income."

Musnik disagrees about a void in the contract and tells Abraham that she would be in breach of contract if she asks the production team to leave. The Nebraska native goes back and forth with Musnik, disagreeing with him, going as far to insult and mock him.

"This is for another show about therapy with my mother," Abraham explains. "It's not about my struggles or me being a teen mom or any of that type of thing."

"How is that different?" Musnik asks.

"You know what's so f--king laughable right now? Larry, I'm laughing," Abraham taunts. "I would love to not laugh in your face. Why are you so white trash?"
