"Sad" is a Sesame Street song sung by Little Jerry and the Monotones. The song talks about how it's ok to feel sad and to cry when bad things happen. Little Jerry enumerates some of the things that he's sad about. At the end of the song, Big Jeffy tells him that's it's ok to cry if he feels sad, but that it makes him sad to see Little Jerry so upset. Everybody else in the group feels so sorry for him that they start to cry as well, leading the whole group to break down in sobs while forming a group hug.
