Urban Legend: Pregnant woman accused of shoplifting a basketball

True.
The full story was far less titillating than one- or two-line summations of the incident made it out to be.
On 13 February 1985, a very pregnant Betsy Nelson of Arlington, Virginia, was detained on suspicion of shoplifting by Irving’s Sport Shop, a sporting goods store in Seven Corners, Virginia. She had gone there to look for a rowing machine to help her get back in shape after the upcoming birth of her child, a joyous event not expected for another full month.
