Citigroup is the banking world's answer to Madonna

Citigroup Inc. (C) reminds me of Madonna.

Both the beleaguered bank and the pop star saw their best years in the 1980s and have evolved into parodies of themselves. Citigroup tried to create a financial supermarket while Madonna writes Kaballah-themed children's books. Using Madonna's career as a guide, Citigroup is probably somewhere between the pop diva's awful cover of "American Pie" and her decision to date a Brazilian model old enough to be her son.
