Returning tonight for its eighth and final season, the hit Showtime series WEEDS promises to reveal who got shot and who the shooter was in last season’s mind-blowing cliffhanger. From the beginning, this twisted comedy/drama about a pot-peddling family trying to beat the system has been a source of glib adult humor and from the episodes we’ve previewed, it’sgoing to be  business as usual this season. Not too long ago, we spoke with series co-star JUSTIN KIRK about his notorious masturbation monologue (from the first season) that remains the show’s most watched youtube moment. KIRK’S delivery of coming-of-age advice to his young nephew (played by ALEXANDER GOULD) remains a classic and he joked that he hopes it did a public service.
