To All Those Happy Pretenders

I've come across and still will hopefully encounter. Hit me by surprise.

I once came across somebody pretending to be an art historian, and some time later somebody pretending to be a philosopher. Looking closer into the matter I confronted the art historian and told him that I thought him to be rather an artist himself, which he flatly denied, but went on provoking people like an artist would do. The philosopher himself admitted that he only took up philosophy because he was jealous of his brother's talent for drawing.

Of late I've come about somebody pretending to be a star. And looking quite close I found that the art historian, the philosopher and the star were actually great artists.
