Tortoise Chasing Peafowl
When the peafowl hopped down into the tortoises lair, the tortoise retaliated. He chased this bird twice around the enclosure, finally caught it's tail and bit a big mouthful of it. The bird got the clue and took off immediately and the tortoise went back to sunning.
This guy was way faster than anyone expected, including the peafowl, and the crowd loved it.
