A Fishing Tip

Two experienced fishermen went ice fishing. They chopped holes in the ice about twenty-five feet apart, put worms on their hooks, dropped their lines in the water, and hardly got a nibble. This went on for several hours, but no luck. Mid afternoon, a schoolboy arrived. He walked confidently onto the ice, chopped his hole between those of the two men, and caught fish after fish.

The men were amazed, and finally one approached the boy and asked, "Tell me, young man, what is your secret?"

The boy replied, "Mmmm yymmm mmms wmmm."
"What's that?" asked the man. "Say it again, please."
The boy said, "Mmmm yymmm mmms wmmm."
The man said, "I'm sorry, I just can't understand you. Would you speak a little more clearly?"

At that, the boy cupped his palms, spit out a large amount of substance into them, and said clearly, "Keep your worms warm."
