Experienced ice fisher has spent an hour at his fishing hole but is not having luck. He sees a kid sitting nearby on the ice pulling in one fish after another out of the water with his pole. Finally the older gentleman trudges over to the kid and asks him, "I've been watching ya kid, what's your trick?"

The kid mumbles with his lips tightly clamped shut, "M-mmm-mmmm-mmm." When asked again the gentleman gets the same response, "M-mmm-mmmm-mmm." Only this time with more emphasis.

Upon asking the third time the kid spits out a glossy sticky worm into his hand and says, "Ya gotta keep your worms warm!"
