Absurdity and Being in "Being John Malkovich"

I was mesmerized by the smaller absurd comments and jokes that are made throughout Being John Malkovich. I think it is interesting that the protagonist works on the 7 1/2 floor, although I am not sure that I completely understand what that is supposed to tell the audience or what kind of argument it is supposed to make, especially regarding performance and identity. But I just loved that at the end of each trip into John Malkovich's head one is thrown out onto the side of the New Jersey Turnpike. As I Jersey girl, I hear a lot of negative jokes about this state, but I cannot help but laugh. I was also amused by the roles that Dr. Lester and his secretary play. But, I guess one line that stood out to me was when Craig's wife says after being in Malkovich's head for the first time, "I knew who I was. I was John Malkovich." This is a perplexing thought. To think that one name identifies you collectively, and then say that a completely different one with a different body, thoughts, beliefs, and almost every other social construction conceivable could sum it up better.
