What's wrong with this picture?

Besides my big fat head barging in, can you guess what's wrong with this picture? Poncho has this funny habit of throwing his toys on the ground behind Mom when he wants to get her attention. Well this morning she wouldn't pay attention to him so he went and got a different toy to throw on the ground. When she finally turned around to see what it was she was sooooo surprised! She thought he was playing with his little tennis ball (it sounds exactly the same as when he was throwing the shoe down). Wrong! Now he's in trouble. I guess for some pups it's true that ANY attention is good attention. This was Mom's last pair of flip flops.............
