Rich Strike came up the rail gunning for an 80-1 upset in the Kentucky Derby on Saturday. The horse was the second-biggest upset in the race’s 148-year history, paying $163.60 to win. He ran 1 1/4 miles in 2:02.61. While being escorted to the winner’s circle, he got a little feisty with another horse. Do horses act like this all the time? Was he juicing?! Was he just celebrating like young, excited horses do?
