In tonight's episode of The Real Housewives of New Jersey, titled, When Joes Collide, Joe Gorga and Joe Giudice have an explosive fight after Gorga insults his sister Teresa Giudice.

The shocking physical altercation began after Teresa confronts her brother Joe Gorga and tells him he's disappointing their family. Joe made her upset when he said he would rather continue to defend his wife, Melissa Gorga, who Teresa has an ongoing feud with.

"Stick with scum like you?" Joe Gorga tells his sister. "She is scum," he tells everyone nearby listening to their argument.

After Teresa storms off and tells her husband what happened and that she wants to leave. Joe Giduice demanded that Joe Gorga apologize to his sister. Instead of apologizing, Gorga rushes Giuidice, and the two men have a fight.

As Teresa, Melissa and several cast members try to tear the men apart, Gorga says in the voice over, that the fight erupted because he had "10 years of anger and hatred built up inside" of him.

A visibly upset Melissa tells the cameras in her confessional that the fight between Joe Gorga and Joe Giudice was the absolute "worst day" and that their feud with the Giudices has officially hit "rock bottom."

The Joes came to blows in Lake George, where Teresa arranged for the Jersey housewives and their husbands to go on vacation together.

She revealed in last week's episode that her goal was to try to get everyone to squash their ongoing feuds with each other.

The rest of the episode's other story lines follow Teresa confronting Jacqueline Laurita and Melissa discussing Teresa's lies to the others. Kathy Wakile, meanwhile, observes all the drama and tries her best to referee the war between the Giudices and the Gorgas.
