The picture above is the real Flo, who looks nothing like the Flo on TV. She's an actress who's real name is Stephanie Courtney. You can read more about her on http://www.imdb.com/.
I guess Flo caught on because there seem to be several new Progressive commercials featuring Flo. My favorite is when she is checking out a couple who is buying boat, motorcycle and RV insurance and the woman comments that they don't have those things, and her husband says, well, yes, they do now. Flo says, "Surprise!" and the woman gives her a look that could kill. Flo says, "Let's bag these up."
I like you, girl. You're funny and self-deprecating and even though I don't have Progressive, we should hang.
