MSNBC's Tucker Carlson, a Dancing with the Stars contestant last year, made a return appearance on tonight's show. In a spoof skit, Carlson — along with fellow ex-contestants Lisa Rinna, Harry Hamlin, and Laila Ali — check into 'dance rehab' (who knew?) in Malibu because they "haven't been able to let go of being on Dancing With the Stars."

"I was brought here against my will," Carlson tells a 'rehab counselor'. "I am a dancer, whether (people) believe me or not.

"I'm the one person in here who doesn't need therapy," he continues, "because I'll never get rid of dance. You could cut me into pieces, and each piece would have dance within it."
