We're down to the Shaven 16 in Jack's March Baldness and what a throwdown we have for you in our featured match-up today. Jamie-Lynn Winkler is the last remaining female contestant and has that whole G.I. Jane/Sinead O Connor thing nailed. But she's facing an unforgiving Mr. Clean Doppelganger in Joe Castro. Something tells me the winner of this round will punch a ticket to the Follicle 4. Voting on the Shaven 16 ends at 3 pm on Sunday.

The winner of Jack's March Baldness can win $1000, but if you vote now you could too.  That’s right, just pick the best bald head and your entered to win one eight-hundredth of a college basketball coach’s salary.
