Another day at Springfield Elementary, another prank. Bart and Milhouse have collected a mass amount of helium filled balloons. What did they do with them? Tied them to a classmate of course. They tied the balloons to Ralph, and he floated away. Principal Skinner quickly found out about their prank and ordered them to undo it quickly. Surprisingly Bart grabbed a bb gun and fired at the balloons, sending Ralph back to Earth. The plan was not thought through thoroughly enough, and Ralph lands on concrete flat on his face and suffers serious injuries. An ambulance is called and Ralph is rushed to the hospital.
