Evil Eye

Evil Eye was a strip about a floating, seemingly invisible ghostly eye which amused itself by turning its baleful gaze on random people and using its influence to make them behave in unpleasant ways in order to cause mischief and get its victims into trouble. Inevitably though, circumstances would conspire against the Eye and its victims' actions would have unintended positive consequences. The Eye could also, despite being invisible and presumably non corporeal, be hurt, and would sometimes end up getting accidentally blacked. A similar strip but with a more benevolent protagonist was 'Orrible 'Ole.
