So WHEN did Brody join a gang?

So last night, the Hills was PRICELESS! Between the Spence and Heidi brawl and the best line ever when Heidi uttered "Don't you mock me!" to Brody showing up to a fine restaurant with his ball cap to the back and a gang banger style plaid button shirt, it might have been the best Hills EVER. And lets not forget Heidi spilling the beans to Spence's sister that she wasn't sure about getting married and then pricelessly telling Stephanie, "Now, don't say anything to Spence, I think this goes without saying, but, like, your his sister". I mean is Heidi really this stupid? SHE'S HIS SISTER - YOU DIMB BULB! I then who can forget Lauren talking about Brody becoming her boyfriend, are you serious, Brody is not settling for an f-list reality star! And Audrina telling LC how great the new bf is, ummm, Audrina, he bought you dinner and then basically told you it was time to go home so you could put out! What a winner! GOTTA LOVE THE HILLS!
