Ken Leaves Barbie for Ben?

Mattel is pushing its line of Barbie dolls by insinuating in tweets and on billboards that the toy character's ex-boyfriend, Ken, wants her back -- but there's a rogue effort to get the blond doll together with another "man."

Aside from tweets like, "How does a doll know when she's thinking about an ex ... and not just memories with him?" Mattel has purchased billboard space in Southern California where Ken asks for Barbie's love back (they "broke up" in 2004). But a website has sprung up featuring a Ken impersonator (with facial hair) standing next to Ben, a moustached doll wearing a sleeveless shirt. A message from Ben reads, "Let's come out with the truth. Ken is head over heels in love with me, Ben Collins. But Barbie is trying to get back together with him. Please help me show the world that our love is real and not plastic."
