Actually, this time it was Jessica who started it. Josh and Paul were discussing the drought. Paul said Josh is responsible for causing the drought because he showers so much. Jessica chimed in to say, "Josh, I bet you can even spell the word drought". Then she asks him to spell it. Josh spells in correctly, and Jess says, "okay, you got that one, but there are 100s of other words I can get you on".
Josh responds by telling her that he does have a college degree, and runs his own business, and regardless what she thinks, he isn't stupid. Jess then replies with, "okay Josh, if you say so".
Josh left the area and went out back to tell others what happened. He talks about how she really disrespected him, and how the conversation didn't involve her, she just jumped in at him.
Josh gets an idea for a comeback. Goes back inside and says to Jess, I have a word for you to spell, "evicted". Then all hell breaks loose and Cody starts to get involved. It got really heated after that. That's the just of it anyway.
