 Mr. Burns reveals that , after leaving the town meeting , he came across Maggie eating a lollipop in the Simpsons ' car . Mr. Burns decided to try stealing candy from a baby , but Maggie would not let go of the lollipop , resulting in a struggle . As he finally yanked it away , his gun slipped from its holster into Maggie 's hands and fired at Burns . The gun and lollipop both then fell beneath the car seat ; Homer would later unknowingly leave fingerprints on the gun while feeling around under the seat for an ice cream cone he accidentally dropped . Lisa guesses that with his last strength , Burns must have pointed at the " S " and " W " on the sundial ( with the " W " appearing as an " M " from his perspective ) , to identify his assailant ; Mr. Burns corrects her , saying that he was actually swallowing his gold fillings to protect them from being pilfered by the paramedics . The " S " and " M " were purely coincidental .
