I love a good throwback commercial—especially of the dance variety.

Lately, having dancers promote your product in the background of your ad is pretty standard. Duh, dancers make everything better.

But casting dancers in commercials is nothing new, and I especially adore when a commercial features great dancers and a "not a girl, not yet a woman" celebrity who can groove right along with them.

Case in point: The 2006 "For those who think young" Pepsi commercial featuring one of my all-time faves, Ms. Britney Spears.

The girl could sing (um, more or less).

The girl could dance (totally).

And oh yes, the girl could sell a product to even a non-soda drinker like myself.

Super-choreographed commercials? Whatever you're selling, I'm buying.
