"This Is My J" is a Sesame Street song by Biff about the letter "J". He sings about how he will always keep his letter "J" and will never leave it behind while backed up by Sully and some other construction workers. Despite his message in the song, however, when it's time for their lunch break at the end of the song, he abandons his "J" and it falls to the ground, damaged.
