Geologist

[Mark Zuckerberg]

Geologists are scientists with an unnatural obsession with geology (rocks). Often too intelligent to do monotonous sciences like biology, chemistry, or physics, geologists devote their time to mud-worrying, volcano poking, fault finding, bouldering, dust-collecting, and high-risk colouring. One of the main difficulties in communicating with geologists is their belief that a million years is a short amount of time and their heads are harder than rocks. Consequently, such abstract concepts as Tuesday Morning and Lunchtime are completely beyond their comprehension.
Geologists in the movies are nothing like the real thing. For example, in a volcanic eruption, or major earthquake, no geologist is going to give a rats ass about rescuing a dog even if it does belong to the romantic interests children. He or she will be far more concerned about the mineralogy of the ash falling from the sky, or the viscosity of the lava flow and its movement across the substrate (which may or may not include a village).
There is a considerable, and still growing body of scientific literature that suggests that geologists are in fact the worlds first alcohol-based life form.
