An en-route Air Ambulance (organ collectiong flight) en-route was told by a controller that the transplant team no longer needed his services and was asked for his intention. The Captain replied "I'll go back home then and requesting to divert", the controller promptly gave a clearance and transferred him to the previous sector where a very cute female voice awaited his arrival.
Unfortunately, the exact circumstances of the Air Ambulance's diversion were not explained to the female controller and 'to be on the safe side' wondered if this aircraft had an emergency. As the aircraft 'checked-in' the female controller asked if he wished to declare and emergency, which prompted the follwoing response "Nope, I am just having trouble finding my organ!". This sparked off a few other equally interesting comments from other crews - order was restored a few minutes later.
