Simba's figured out that when we go to the dog park, I grab his favourite blue football out of the trunk of the car. So now instead of waiting for slowpoke me to grab the ball, he'll just hop into the trunk, grab the ball and jump out. The people at the dog park thought it was pretty funny when they saw him jump into the trunk.
What's even better is that sometimes when we're leaving, he'll jump into the trunk to put the ball back and then jump back out. Most of the time though he'll just jump in to try and grab one of the other toys we stash in there.
