Two men have been sitting out on a lake all day long, ice fishing. One has been having no luck at all and the other has been pulling fish after fish out of his hole in the ice. The man having no luck finally leans over and asks the other what his secrect is.

"mmmmm mmm mm mmm mmmm mmm mmm."
"I'm sorry, what did you say?"
"mmmmm mmm mm mmm mmmm mmm mmm."

"I'm sorry, I still didn't understand you." The successful man spits something into his hand.

"You've got to keep your worms warm."
