When Terry came into work today we all noticed that his car was running very well and the usual squeaks and rattles had been replaced with a cacophony of cheery little chirps.
Terry proudly informed us that he had had his car coverted to new state of the art Sparrow Power. The emmisions are neglibible with no nasty pollutants and zero CO2 and the only outcome is the steady repopulation of our depleted House Saprrow population...
No CO2 but the particulate fall-out might be a problem!
