Conventional science contend that this creature functions solely on brain stem activity and uses the space otherwise occupied by a hominid brain as a "beer sponge". The creature has little capacity for memory and must always wear clothing with its name stenciled/stitched on the clothing. This condition of uncommon stupidity is aggravated further by the excessive consumption of 'ludes and alcohol during University of Texas tailgate parties. Behavioral exhibitions of this creature include: Standing around a drooling, lighting flatulence near open flame, and throwing objects at the highly-valued property of others.
