Recently I came across a photo of Kelly Ripa as "That Girl"

Any other imitations, spoofs, etc. that you can recall?

Roseanne did a spoof of Father Knows Best, King of Queens did a spoof of the Honeymooners (a pretty good one!); Wayans did one of Good Times.

There was a mini "That Girl" spoof on "Roseanne." In the episode, "Satan, Darling" Roseanne agrees to drink the witches' brew, but only from "That Witch." That Witch is guest star, Marlo Thomas:

Family Guy did a spoof in the episode Mr. Griffin Goes to Washington. In it they say "That Guy" and its basically Peter Griffin as Ann Marie in the theme song. Funny as Hell ;)

In the mid-80s Saturday Night Live did a couple of "That Black Girl" sketches with cast member Danitra Vance (http://splitsider.com/wp-content/uploads/2013/01/danitra_blackgirl02.jpg).

According to the page on Wikipedia:

"The show's theme song and opening visuals have been parodied in pop culture several times. They appeared as a series of T-shirts, then as a Saturday Night Live skit featuring cast member Danitra Vance in an African American remake "That Black Girl", as a sequence on episodes of Animaniacs, The Simpsons, Family Guy, Clarissa Explains It All, Arthur, Friends and Roseanne."

Thanks for starting this thread biffbronson! It's been interesting reading about the various spoofs. I just found the list below on IMDB (http://www.imdb.com/title/tt0060034/movieconnections). It looks like "Roseanne" spoofed "That Girl" twice. In the episode I mentioned earlier and in "Call Waiting."

I've been dying to see that.

I've seen that, and it isn't much of one.
