This is yucky and sad. A guy was arrested after trying to get into the studio where DWTS is filmed by climbing over a fence. He was nabbed by security, and claimed that he was there to see Shawn Johnson, who of course had never heard of him.

After he was arrested, it turned out he had guns, duct tape and Shawn memorabilia in his car. (!) He was held on bail and Shawn's family has filed a restraining order.
