Grace and Frankie Get Into the Vibrator Business in Season 3 Trailer

It's not always easy going into business with your best friend, even if that business is selling vibrators for older women; taking into account their arthritis and tender vaginal tissue, of course.

In the trailer for the new season of Grace and Frankie, Grace (Jane Fonda) is having trouble sharing the reins with Frankie (Lily Tomlin) on their joint business venture. Frankie doesn't appreciate being swept aside on all the business decisions, so a rift develops in their newfound friendship.

Of course, during all the straight drama Sol (Sam Waterson) and Robert (Martin Sheen) are settling into a new house, and contemplating retirement so they can spend the rest of their lives together in comfort. Watch, below.
