从朋友那儿得来这个joke, 很搞笑哦~

Newton, Pascal, and Einstein are playing hide-and-go-seek in heaven.
Einstein closes his eyes and starts counting.
Pascal goes and hides behind a cloud.
Newton stays where he is, and draws a 1 m x 1 m square on the floor around him.
Einstein finishes counting and turns around.
"Ah ha, Newton! I found you!"
"No you haven't, you've found one Newton over 1 m^2 . . . You found Pascal."
