Spinning Out of Control

I was kind of into the movie to see what crazy Natalie Clark was going to do with all of the people in the movie just to get next to simple, delusional, absent minded Leah until crazy, dysfunctional, etc, etc Natalie Clark said these desk "monkeys". I know it's just a movie, but I mean you couldn't have came up with a better or suitable word for her say or use instead of "monkeys" or maybe I'm just looking to far into it, just taking it out of context. Who put that word in the script? Who actually thought that word would be a good, wonderful idea for her to say such a word in a movie like this.
