Looney but lovable That’s ’70s Show star Ashton Kutcher joins the reality parade on Saint Patrick’s Day eve with Punk’d, on MTV. Mr. Kutcher, a 25-year-old former model who hails from Iowa, is both star and producer (with Jason Goldberg) as he pulls what are described as “devilish pranks” on various celebrities, starting with Malcolm In The Middle’s Frankie Muniz, soon to be seen on the big screen as Agent Cody Banks. Kutcher says he is ready to “take down his celebrity friends,” adding: “Well, they were friends. Until they got Punk’d.” Other victims include Kid Rock, Pamela Anderson, Christina Aguilera, Denise Richards, Kelly Osbourne, Mandy Moore and boxer Oscar De La Hoya.
