Aspergic bushbaby Syndrome

Asperger Syndrome or (Asperger’s Disorder) is a neurobiological disorder named for a Viennese physician, Hans Asperger, who in 1944 published a paper which described a pattern of behaviors in several young boys who had normal intelligence and language development, but who also exhibited autistic-like behaviors and marked deficiencies in social and communication skills.

Except for his apparent lack of "normal" intelligence and language development, the bushbaby fits the description.

Perhaps he's exhibiting a new form; let's call it the aspergic bushbaby syndrome, the same as Asperger Syndrome, but to be found in middle-aged men of below-average intelligence whose language development shut down in early adolescence and who also exhibit obviously autistic behavior (particularly facial expressions) in public appearances (at which "normal" people would be embarrassed) as well as extreme deficiencies in social and communication skills, particularly with the press and anyone with other ideas, more education, or multinational experience.
