Penny Marshall and Cindy Williams, who starred in the popular 1970s and early 1980s sitcom, are reuniting for an upcoming episode of Nickelodeon's "Sam & Cat," the network announced this week.
They'll be playing the feuding creators of the "Salmon Cat" show, who Sam (Jennette McCurdy) and Cat (Ariana Grande) must try to reunite. This will be the first time in more than three decades that Marshall and Williams have worked together on a scripted program.
Like "Laverne & Shirley," Nickelodeon's "Sam & Cat" is a spin-off show about two roommates who work together. But instead of working as bottlecappers at a brewery, Sam and Cat run their own babysitting business and have wacky adventures.
The episode guest-starring Marshall and Williams filmed in Los Angeles this week. Nickelodeon has not yet announced when the episode will air.
"Sam & Cat" airs Saturdays at 8 p.m.
