A lack of board certifications. The DA made a mistake by asking the trick question and subjecting himself to embarrassment in front of the jury. He should have then asked whether she regularly studies automobiles and works on cars in the course and scope of her hairdressing career, and establish that while she is familiar with cars, she can not be held out as an expert without the certifications.

Also, her relationship with Vinny would have been explored if she hadn't ruined the prosecution's case.


One of the funniest scenes in that movie was when she resisted testifying and said, "I hate him." about Vinny and the judge said, "I can see that."

This scene (and three or four other movie trial scenes) was used in a continuing legal education course I once attended.
