"Remember Wenn" was a TV show about people who make TV shows, kind of like a show about making a show! The people who make the show are called "producers" and "writers" and they come up with ideas for what will happen on the show. Then, actors and actresses come in and act out the scenes that have been written for them.
The show "Remember Wenn" was special because it took place in the past, a long time ago. So the characters dressed in old-fashioned clothes and used things that people used a long time ago, like old telephones and typewriters. This was called a "period piece."
Even though "Remember Wenn" was a show about making TV shows, it was still a lot of fun to watch. You could see how a show gets made and all the things that go into it, like actors practicing lines and cameras being set up.
In short, "Remember Wenn" was a TV show that showed how other TV shows are made and it took place a long time ago with vintage clothing and equipment.
