It was a cold winter day. An old man walked out onto a frozen lake, cut a hole in the ice and dropped in his fishing line. He was there for almost an hour, without even a nibble, when a young boy walked out onto the ice and cut a hole in the ice not far from him. The young boy dropped his fishing line and minutes later he hooked a largemouth Bass.
The old man couldn't believe his eyes but chalked it up to plain luck. Shortly thereafter, the young boy pulled in another large catch.
The young boy kept catching fish after fish. Finally the old man could take it no longer. "Son, I've been here for over an hour without even a nibble. You've been here for only a few minutes and have caught a half dozen fish! How do you do it?"
The boy responded, "Roo raf roo reep ra rums rrarm."
"What was that?" the old man asked.
Again the boy responded, "Roo raf roo reep ra rums rrarm."
"Look", said the old man, "I can't understand a word you're saying."
The boy spit the contents of his mouth into his hand and said, "You have to keep the worms warm!"
