The fable of the cow

A bull was bitten by a mouse and the wound was very painful. He wanted to catch the mouse, but the mouse immediately hid in the hole, so the bull used his horn to dig the wall. The mouse looked out of the hole for a while, sneaked up to the abdomen of the cow, took another bite, and quickly retreated back into the hole. The bull got up in pain, anxious and angrily not knowing what to do. The mouse murmured: "The big one won't necessarily win. Sometimes the weak and lowly are the most capable of pranking!" 
