See a Doctor
A man goes to the doctor and says to the doctor:
“It hurts when I press here.” (pressing his side)
“And when I press here.” (pressing the other side)
“And here.” (his leg)
“And here, here and here.” (his other leg, and both arms)
So the doctor examined him all over and finally discovered what was wrong... “You've got a broken finger!”

A Picture Is Worth...
The husband says to his wife, “You always carry my photo in your handbag to the office. Why?”
She says,“When there is a problem, no matter how impossible, I look at your picture and the problem disappears.”
He laughs and replies, “You see, how miraculous and powerful I am for you?”
She calmly replies,“Yes, I see your picture and say to myself,‘What other problem can there be greater than this one?’”

Train Of Thought
Aunt Lenna and I went down to the train station to pick up a friend. On the way, she came up with a little puzzle for me.“Let's say that two sets of train tracks run right alongside one another... until they get to a narrow tunnel. Both tracks won't fit, so they merge into one track(合并成一股道) for the whole length of the tunnel... then go back to being parallel tracks(平行的两股道). One morning a train goes into the tunnel from the east end... and anther goes into the tunnel from the west end. They're traveling as fast as they can go, in opposite directions, but they don't crash         . Can you tell me why not?”
