"Mad Goat Song" is an animated Sesame Street song in which a goat undergoes repeated annoyances. A dog pulls the goat's whiskers, and then a cat sets off a loud firecracker. A duck makes faces at the goat, and finally a pig refuses to share his ice cream with the goat. The lesson of the song, as specified in the chorus, is that anger can sometimes be a healthy outlet, and when justified, "it ain't bad to get mad."
