The humans want me to chase a ball, bring it back to them and then chase it again. Rinse, repeat. What is this, some new kind of torture? I see other dogs doing that and I take their ball to show them how to really have fun. I mean, sure, it’s fine to leap and jump after a ball every now and again, but really, what fun is a ball if you can’t tear it into tiny pieces and possibly eat some of them. You haven’t lived until you’ve chewed on tennis ball rubber!!
Humans are strange creatures.
