'Dancing With the Stars' should stay away from guest judges like Abby Lee Miller

Looking for ways to boost the numbers in its 18th season ABC's "Dancing With the Stars" has featured a bunch of guest judges -- from Robin Roberts to Ricky Martin -- to help Carrie Ann Inaba Len Goodman and Bruno Tonioli critique the celebrity dancers. Something's going right because "DWTS" is actually up a bit in ratings from last year averaging around 14 million viewers per episode.
