Q: What's the difference between a monkey and a flea?
A: A monkey can have fleas, but a flea can't have monkeys.
猴子会和跳蚤有什么不同呢？你可能会直接的想到它们俩是一大一小。但除此之外呢，那就是猴子身上可以长跳蚤，而跳蚤身上却不能有猴子。这个答案很有意思吧？
Q: How can you most irritate a farmer?
A: By treading on his corn?
如果你踩了农夫的玉米或是谷物，他肯定会生气的；而如果你踩了农夫脚底的鸡眼，他会更生气。Corn既可以表示“玉米/谷物”，也有“鸡眼”的意思。
Q: Which is the strongest creature in the world?
A: The snail. It carries its house on its back.
因为snail（蜗牛）的后背上总是背着一所房子，所以说蜗牛是世界上最强壮的生物是不足为奇的。你说呢？
