One day, Zen Master Man Gong sat on the high rostrum and gave the speech to mark the end of the three month winter retreat. "All winter long you monks practiced very hard. That's wonderful! As for me, I had nothing to do, so I made a net. This net is made out of a special cord. It is very strong and can catch all Buddhas, Patriarchs and human beings. It catches everything. How do you get out of this net?
Some students shouted, "KATZ!" Others hit the floor or raised a fist. One said, "The sky is blue, the grass is green." Another said, "Already got out; how are you, great Zen Master?" From the back of the room a monk shouted, "Don't make net!"
Many answers were given, but to each Man Gong only replied, "Aha! I've caught a BIG fish!"
