Here's a little video I shot on my mobile phone of Jaspar and Leo playing fetch out at Dog Training Ireland's great facility. We were out there on Good Friday playing on the agility equipment (which you can see set up in the background). They love to jointly bring back this fetch toy -- you can see them both running back together. Then Jaspar has to 'kill' it. They could do this routine 200 times and never get tired. It's a Quicktime video.
