Christian Stoinev and Scooby perform on America's Got Talent 2014 (VIDEO)

Christian Stoinev and Scooby performed on America's Got Talent 9 Quarter Finals #3 on Tuesday, August 12, 2014.

This was such a charming act that put a smile on my face a mile wide. Christian is an outrageously talented balancing performer, showing incredible precision and grace. And Scooby is even more impressive, balancing on Christian without stumbling or falling. I was actually pretty terrified for Scooby in several points, as he seemed a bit shaky balancing on Christian's feet. But he managed to keep it together long enough for the big finale, as Christian planks and Scooby sits up. The act is adorable and also surprisingly exciting, and well deserving of the standing ovation from all four judges.

-Mel B says she was scared for the dog, despite knowing how well-trained he is. However, she loved the act, and notes what an amazing night this has been. Heidi is similarly enthusiastic about the performance, saying she really enjoyed Scooby, and that Christian is "not too shabby" either. Howard, however, takes it a step further and proclaims this his favorite act of the night. And I can't really fault him for that there. Howie echoes Mel B's sentiments in talking about what an outstanding night this has been, before applauding Christian and Scooby.
