Columnist Floyd Norris has a fun challenge: Name a penny stock that has become a big and important company. And not just a company, successful now, whose split-adjusted price was pennies years ago. Floyd wants a company that was really trading at pennies way back when, and grew to be big and important. For what it's worth, we should probably also disqualify hot-hot stocks like Timminco.

Got it? Okay -- one, two, three .... go!
