I myself thought briefly of doing this idea. I also thought of doing something on the medieval idea of the 'Four Humours'. But I didn't, because I foresaw I would get the reaction that you in fact did. However, I thought it was a funny play, with much of the humor deriving from the plays on terminology.
You have done a fine job simulating parts of the ocular apparatus with your cup. My only real suggestions would have been to a) use a smaller aperature for more DOF and b) if possible, manually focus on the top of the water to ensure foreground focus.
I am curious as to how you rendered the color. Was that a white balance effect? I am also curious about the hidden message.
Not even knowing what I'm looking at, I didn't laugh. I'm sure someone will maybe find it funny, but heck, I don't even know what it is. I guess this is a photo for only a certain group of people. I can't even comment on the focus or angle or lighting or anything. Sorry.
