Funnyman Seth Rogen has been hired as rapper Waka Flocka Flame’s joint roller after applying for the job online.

The Knocked Up star spotted the hitmaker's ad for a "blunt roller" earlier this week and took to Twitter.com to offer his services.

He wrote, "@WakaFlockabsm #icanroll Hit me up", prompting the rapper to respond Rogen had been "hired" for the position, which pays $50,000-a-year.

Rogen has become a stoner icon in recent years and regularly advocates the use of marijuana in his films.
