Paul Felder's recent fight against Edson Barboza comes to mind. Actually, it looked like he thought two of the judges might be stupid enough to make the wrong decision and was hoping they did and would keep his undefeated record intact. Then as soon as it's announced as a unanimous decision it's like you can see the wheels in his head turning, "You mean UFC judges aren't all idiots? SHIT!" Anyway, looking for better and funnier examples.
