“Joan & Melissa: Joan Knows Best” Season 4 premieres Saturday, March 29 at 10 p.m. on WE tv. A preview video for the upcoming season makes it clear that the Rivers women are up to no good in the most insane of ways.

Things featured in the video include: talk of a sex tape, possible drug use, Joan Rivers in an electric wheelchair cart, walking in on sex, Tara Reid, tropical birds, fighting and zombies. Yes, there are zombies in Season 4.

What else will happen in the new season? Considering the promo, it could be just about anything.
