A new executive went to his first high-level meeting. At the end of the conference table sat a fellow who, whenever a tough problem came up, would say something like, "Well, it never rains, but it pours" or "It's a long road that has no turning" or "If life gives you lemons, then make lemonade."
"Exactly what does that guy do?" the new executive asked a colleague after the meeting.
"He gives us our spirit of unity," answered the man. "We'd all like to strangle (掐死) him."
以上幽默，我根本不知道它幽默在何处。

西方的幽默确实与东方的有很大的差异，这是文化差异造成的。
这故事大致是讲一个职员在公司有困难来临时总是泼冷水，新执行官好奇他是干什么的，他的同事就说“他给我们团结的力量，因为我们都想掐死他。”他的可恶甚至让所有的fellows都同仇敌忾，团结起来，这应该算是外国人所认同的一种幽默吧。
