The dog story:
There was a dog playing the role of mascot of the congress . This poor animal wanted to play with some of the participants. One of them was presenting a poster but had not really the same point of view... So the kind dog managed to grap the poster on one side and the guy the other side ... it turns out that a part the poster's conclusions ended in the mouth of the dog which ran away... and dig a hole to put it in the earth ... after that, the dog came back to the poster area and grabbed the camera of the guy... the dog apparently wanted to put it as well in the earth. I missed some parts of the story but it is funny anyway.
sit...sit........ good dog!
