Jerry Springer

From OAPedia.com

Talk show host Jerry Springer was a guest on The Opie and Anthony Show while he was doing Dancing with the Stars in 2006. As a goof, O&A asked the Pests to vote for Jerry to continue with the competition. Partly due to the Pests, Jerry managed to stay on the show for a few more weeks, though he wanted out badly - his knees were killing him.
