Joan Rivers is the best, because she's brash and hilarious and plainly doesn't give a crap what anyone thinks about her as she continues to work her ass off well into a storied comedic career. But legends need relief, too: on last night's episode of Joan & Melissa: Joan Knows Best, she gets stressed out because her daughter's boyfriend's parents are in town, and she doesn't know how to properly deal with them. Coming to the rescue, her friend Lynne suggests the only appropriate cure: medicinal marijuana. Perhaps motivated by the reality cameras behind them, the two ladies get to a dispensary to score before parking somewhere and sparking tree. The clip, which you can watch after the jump, is amazing.

"I've got to eat something," Joan says with total awareness. Too baked to drive, they call her daughter, Melissa, to come pick them up. Melissa promptly freaks out because her mom can't stop babbling about how nice her hair is. "My 78-year old mother has become 17, and I've become a soccer mom yelling at her teenage kids," she whines in a confessional. "You're so bitchy!" Joan cackles as Melissa shuffles them into an SUV. But I don't want to spoil all of it, because the video is only ten minutes long and you should watch it now. Just know that eventually, Joan starts drinking water out of her shoe, after she's gotten into a hot tub with all of her clothes on. Viva Joan forever.
