Jenny on wheels

You spot a woman take her toddler out of a large stroller. She puts the toddler on her shoulder as the child was fussy. You smile and click your fingers.

The stroller rolls out in front of Jenny. She sees it, but her momentum does not allow her to stop in time and she pitches head long into the stroller. The stroller is sturdy, the kind one can jog with, and it rolls down the mall with Jenny's upper body in the carriage and her butt and legs sticking out with her soggy panties sliding down a bit more. There is no way for Jenny to stop the carriage.
