Billy Bob and Jethro decide to go ice fishing. After arriving at the lake early in the morning, they cut two holes in the lake and drop in their lines in the water. After fishing for a few hours, Billy Bob has caught dozens of fish while Jethro hasn't even gotten a bite. Jethro asks, "Billy Bob, what's your secret?" Billy Bob answers, "Mmu motta meep da mmrms mmrm." Jethro asks, "What did you say?" Billy Bob answers, "Mmu motta meep da mmrms mmrm." Jethro again asks, "What?" Billy Bob spits into his hand and says, "You gotta keep the worms warm!"
