My Ding-a-Ling Kid is a student at Springfield Elementary School who participated in the Springfield Elementary School Talent Show where he starts singing a crude rendition of Chuck Berry's "My Ding-a-Ling." Shortly after he starts he is promptly stopped and escorted off stage by Principal Skinner. He is voiced by Tress MacNeille.
This character bears a strong resemblance to Chuck.
