Only a couple days into the Olympics, and there's been a nip slip.  It belongs to . . . 22-year-old Urantsetseg Munkhbat, a 106-pound judo competitor from Mongolia. 

--She was competing against Paula Pareto of Argentina yesterday, when Pareto yanked on her shirt, exposing her right nipple . . . to whoever happened to be watching live streaming judo online at the time.  It wasn't broadcast on NBC.

--Munkhbat went on to lose the match, and didn't win a medal.  Pareto also failed to medal.
