well.. hmmmmz..
first I think they train the dog.
then I think they videoed him
then they wrote some script voodoo language stuff so that each video is labeled with a simple dog command to play... (though potty and outside he doesn't understand)
then I think they put it up so that schmucks like me could be reminded that cats are so much more devious.. LOL
*grins at Mistress, bounces a little and asks*.. how was that?? *G*
