The skinnier, slightly more rat-faced Olsen has just landed her first co-starring television role without a prominent catchphrase, on Showtime’s dark comedy series “Weeds.” From the Hollywood Reporter:

“Weeds” marks Olsen’s first major solo role. Since their debut on ABC’s hit comedy series “Full House” at age 9 months, Olsen and her twin sister, Ashley, have starred together in a string of kids and tween-oriented series and movies for television and video.

Olsen’s role on the edgy Showtime series about a pot-dealing mom (Parker) also is a departure from the wholesome, PG characters she and her sister have played and opens a new chapter in her acting career.

That’s funny. I would bet that Mary Kate’s drug of choice smacks more of the powdered variety. Personally, I can tell you that back in my own pot-smoking days, a typical “post doob snack” would run the gamut of a family-sized sausage calzone, a pound of pistachios, a box of Swiss Cake Rolls and a large bag of Fritos “Scoops” dipped in ketchup. But I’m pretty sure not even one of those food items would fit inside an Olsen. I know it’s TV and all, but even for fiction, that’s asking a lot.
