If you're a fan of '70s and '80s TV, you've probably been having a bunch of a "wha the?" moments over the last year or so. When this particular little white-haired older lady shows up on a show, she doesn't look familiar, but then you hear the matronly but deep voice, and you realize who you've just seen on your screen.

It's Mrs. Garrett! Only by the time you realize it, she's gone, leaving you to wonder if you were imagining things.

Don't worry; you're not going insane. We've been seeing a lot of Charlotte Rae, who played Edna Garrett on Diff'rent Strokes and The Facts of Life, on TV lately, mostly playing tiny roles that involve maybe a few lines at the most. In fact, just last night, she played a suspect's mother on an episode of Life.
