It's a very happy anniversary on "Fuller House."

The third season of the Netflix sitcom begins premiering Friday, Sept. 22 — the very day that the original series, "Full House," debuted 30 years ago!

It's the day Jesse (John Stamos) and Joey (Dave Coulier) moved in to help Danny Tanner (Bob Saget) raise his three daughters.

Now, of course, his eldest D.J. (Candace Cameron) is raising her three boys with the help of sister Stephanie (Jodie Sweetin) and BFF Kimmy (Andrea Barber). And Season 3 looks to hold more hijinks, relationship drama, and catchphrase callbacks. Plus, the OG cast members return to celebrate the big day (except for Mary Kate and Ashley Olsen — they're still no-shows as Michelle).

Season 2 ended with D.J. helping ex-boyfriend Steve propose to his girlfriend C.J.; Stephanie falling for Kimmy's brother; and Jesse and Becky (Lori Loughlin) adopting a baby girl.
