If You Want the Best Chance At a Baby Born On 11/11/11, Have Sex Today
 

Today is February 11th, exactly NINE MONTHS until it's November 11th, 2011 . . . or 11/11/11.  So, if you want your baby to have that birthday . . . which really would be a cool birthday . . . then, uh, stop listening to the radio and get to humpin'.

If you don't have time today, this entire Valentine's Day-through-President's Day window should work.  For example, if you conceive as late as the 18th, you're still on target for a November 11th due date.  Get to it.
