Nickelodeon will host an unforgettable night on Nov. 9 with an iconic reunion of legendary television creator/actor/producer Garry Marshall’s landmark series, Laverne & Shirley and Happy Days, in a brand-new episode of Sam & Cat!

In Sam & Cat premiering Saturday, Nov. 9, at 8p.m. (ET/PT) on Nickelodeon, beloved comedy duo Penny Marshall and Cindy Williams (Laverne & Shirley) will reunite on screen in a scripted series for the first time in over 30 years. In “#SalmonCat,” (Jennette McCurdy) and Cat (Ariana Grande) are ordered to rename their babysitting business because it’s too similar to “Salmon Cat,” a TV show from the ‘70s.  Sam and Cat must track down the show’s two original creators (played by Penny Marshall and Williams) and resolve their three decade-long feud.
