"Mr. Opportunity," the cartoon pitchman for Honda Motors.
They trot out this retard with bad hair every year for their end-of-model-year-clearance sales. "Annoying" doesn't begin to describe this figment of a very disturbed person's imagination. One of their bits is having him "knock" so that it seems as though he is knocking on the inside of your TV's cathode-ray tube, which makes no sense as more and more folks switch to LCD and plasma sets.
May this character be run over by Roger Rabbit.
