Also on Fox Sunday night: David Cassidy played a Las Vegas headliner on Malcolm in the Middle.

His character opens his act singing Pink's "Get this Party Started" -- then moves into Madonna's "Papa Don't Preach." ("She's keepin' my baby").

"We're keepin' his baby," the chorus of showgirls sings.

As the show ends, Malcolm tries to forget that his mother slipped backstage to the lounge lizard's dressing room. Which is hard to do, as the mother insists on listening to a tape of the David Cassidy character covering a Bad Company song.
