DBoz - The humor lies in the fact that the Holga is a plastic body/plastic lens 35mm camera (with one f/stop as Wells points out) often used for its "artistic" abberations, etc. and it's placed next to a very expensive and nice Sekonic digital light meter.
My reply was intended to play upon his benign question by responding as if the lighting of the camera was "what was wrong with this picture". Get it? Got it? Good!
