This State Farm commercial has been running for a while now. Though it is humorous and at first it may not seem offensive, I think it relies on and enforces gender role stereotypes. It portrays the women as two extremes. The wife is the paranoid, jealous woman that the audience is set up to dislike. The circumstances are such that she appears annoying and crazed. The hypothetical woman she suspects is on the phone with her husband is another stereotypical woman – the mistress.
If the husband were indeed cheating on his wife, he would be the disliked character in the situation. However, the revelation that he is in fact speaking to a male State Farm agent makes him the innocent, noble one. The way the situation is portrayed makes the audience root for the man and against the woman.
While I think that this ad is mostly degrading towards women I can also see the argument that the man is stereotyped as well. He appears, at the beginning, to be a sleazy cheater. The commercial clearly depends and plays on gender stereotypes in the audience.
