LOL! Clever Heyoka!

Reminds me of a dog I used to have, Blue. He used to open the back door both ways. He would let himself, and the other two, Duke and Max, in and out all the time. Then I got smart and started locking the door, but he would still check every now and then. Of course sometimes I would forget and discover dogs in when they should be out, and out when they should be in!
By the way, Blue was a Lab/GSD mix and a real character!
