NEW YORK—According to sources, the people in a commercial for the Canon PowerShot S1100 IS digital camera have expressed a degree of pleasure that far exceeds the enjoyment that any known consumer electronic device could possibly provide. "Despite what we're seeing in this commercial, no existing camera is capable of producing the increased release of serotonin and dopamine that these people appear to be experiencing," said Dr. Otto Hauser, a brain and cognitive sciences professor at New York University. "Features such as red-eye reduction and night display would perhaps trigger a very brief elevation of mood, but oh, come on! They just high-fived, for Christ's sake." At press time, Hauser said the level of fun that the camera is providing has outstripped what would be even remotely attainable with a Jet Ski–brand watercraft and a 12-pack of Samuel Adams premium ale.
