I like this picture of a French customs officer playing with his sniffer dog in a deserted Charles-De-Gualle airport as the ash from the Icelandic volcano, Eyjafjallajökull-göes-bööm, continues to ground flights across northern Europe.

Meanwhile, staying with northern Europe and, of course, sniffer dogs, this four legged explosives expert joined his handler recently as they took part in a NATO exercise in Norway.

Man, cats seem really useless now…
