Duck and Crab Race

鸭子和螃蟹赛跑,一起到达终点，难分胜负，
裁判说：你们来个剪刀石头布吧
鸭子大怒：妈的，算计我，我一出总是布，他总是剪刀。

Duck and crab finish in the same position in a race.
The judge says, "You will play scissor paper stone to see who's the winner."
Duck raises his voice and scream, "Bastard! You are plotting against me! I can only show 'paper' and he will always show scissor!"
