chessy lines?

Rating: Null/10 (2 May 2006)

I was just wondering what the reason for so many Attempts at comedy in this movie. I know there was some comedic moments in t2. However, t3 was filled with so many chessy(funny) lines. This was written by Cameron wasn't it? Did he decide that this was going to be comedy instead of sci/fi action. Or where those lines added behind his back by the diector? I have a feeling that they were suggested by Arnold during the shooting and that Mostow is such a pansy that he didn't stand up and refuse to have those ridiculous lines in the movie. Don't get me wrong I love Arnold but I have seen interviews where he attempts to be funny and they turn out surprisingly similar to the chessy feeling of T3.
