This sibling rivalry came to a head when Teresa and Joe failed to work things out at the gym. And by fail we mean have a huge public fight where you scream and throw water at your sibling.

Possibly the most intense brawl in Bravo history, this Joe vs. Joe showdown was one fight we'll never forget. Not exactly ideal retreat behavior.

Ah, the moment that started it all. After the prostitution whore table flip, New Jersey would never be the same.

In what Caroline referred to as Jacqueline's 'a-ha moment,' Teresa blamed Jacqueline for the stripper-gate fiasco with her brother and Melissa. Who set who up is still unclear, but one thing's for sure--these two were never the same.

If there's one thing the New Jersey wives know how to do, it's have a fight in a parking lot. Melissa and Teresa were no different when they went toe to toe outside a summer solstice party. Even their third eyes were seeing red.

The tension heated up between Caroline and Teresa when Caroline confronted Teresa about putting insults in her cookbook about her son Christopher. Teresa denied any cruel intentions, creating an explosion that rocked this friendship forever.

After a 15 year friendship, the bond between these former best friends finally cracked for good in a blow out that left Teresa wanting to punch Jacqueline in the face. Not that she would do that or anything.

Three little words from Teresa Giudice started one big Danielle Staub fight. Teresa saying, "Is bitch better?" caused a chaos at the country club that ended in the infamous Danielle hair pull by Jacqueline's daughter, Ashley. Love and Light.

What could go wrong at a Christening? Apparently, a lot. This battle of the Joes was quite the introduction to the Gorga-Giudice family drama.

Here's a tip, if you want to have a calm and productive discussion with Teresa, don't bring up her children. Unfortunately, Kathy did just this, causing a huge cousin vs. cousin meltdown fueling fiery family feud.

Caroline Manzo does not suffer fools. So when Kim G. started to cause drama at the Gorgas' Christmas party, Caroline shut her down in pure Manzo fashion. She then had Kim G. kicked out and let's just say it was quite a dramatic exit.

As if the trip to wine country wasn't already full of drama with a certain phone call to Joe Giudice, fighting erupted when Caroline took on Teresa one last time. This argument ended with Teresa storming out, and Caroline feeling like she was arguing with a sociopath. Yikes.
