A Kong-An very apropos to this post:
Three monks, who had all taken a vow of silence, were walking along a path. One monk, out of the blue, say's, "I have held my vow for two years as of this day!" The second monk, hearing him, say's, "You fool, now you have broken your vow!" The third monk say's, "Ha! I am the only one who did not speak!"
