It was a cold winter day when an old man walked out onto
a frozen Lake Erie, cut a hole in the ice, dropped in his fishing line and
began waiting for a fish to bite.

He was there for almost an hour without even a nibble,
when a young boy walked out onto the ice, cut a hole in the ice not too far
from the old man and dropped in his fishing line.  It only took about a
minute.  WHAM!  A largemouth bass hit his hook and the boy pulled in the
fish.

The old man couldn't believe it but figured it was just luck.  But the boy
dropped in his line...and again, within just a few minutes...pulled in another 
one.

He went to the boy and said, "Son, I've been here for over an hour without 
even a nibble.  You have been here only a few minutes and have caught two 
fish!  How do you do it?"

To which the boy responded, "Roo raf roo reep ra rums rarm."

What was that you said?" the old man asked.

Again the boy responded, "Roo raf roo reep ra rums rarm."

"Look, son" said the old man, "I can't understand a word you're saying."

So the boy spit a wad into his hands and said, "You have to keep the worms 
warm!"
