December is a busy month for Minneapolis humorist Kevin Kling. He just released a new compact disc of his National Public Radio commentaries called "Wonderlure" -- a few weeks from now he'll reprise his role of Joseph in what's now become an annual holiday pageant at the Southern Theater -- and this Monday, Kling returns to the Guthrie Theater to spin more wacky childhood yarns in "Tales From the Charred Underbelly of the Yulelog." Kling says the Guthrie show takes a somewhat jaded look at the holidays.
