Let's face it, acting-wise, Mos Def will never top his appearance on Yo Gabba Gabba! last year. It was just too outrageous and awesome for him to ever outdo. Yet, he is still looking for acting gigs, with his latest being a role on Showtime's Dexter. Sidenote: Apparently he isn't the only new face on the set as Colin Hanks announced that he is joining the cast, too. Shooting for the series' sixth season begins two weeks from today in Los Angeles and you can expect to see new episodes later this summer.
