电影里拓展出书中没有的情节，很搞笑。最欢比尔描写他表外婆的一段。信中仅说”I live with my great aunt who is 75. I think if you had seen the look of delight on her face when I brought the meat and tin of tongue, you would have realize how grateful we are. “想象中是很和蔼的老奶奶，满目慈祥开心的表示感谢。结果出场一个性情乖戾的经典范例，开口满嘴嫌弃。大跌眼镜的同时，我和猪宝想，比尔是在说善意的谎言么？结果结果，老太太坐在桌前看到肉以后，真的是整个天空星星都亮了，开心的像一只小喜鹊。前后的反差，实在是太妙了。
