I came down on the side of shrubs.
My fourteen year old daughter took a multiple choice career placement test at school and the form listed potential careers given the interests she indicated. The third career listed for her was "pharmacologist" and I immediately thought of Spectralbovine. I don't lend too much credence to this test, however, because her best friend checked off on her career form that she enjoys making people laugh, and the response she got back was that she should be a clown.
