When Ernie is singing his song about his love for adding, Bert comments, "Ernie, this is not normal, you singing like this." Not normal? Oh, I had no idea that busting out into a random song about subject matter on Sesame Street was not normal, especially all those songs Ernie randomly broke out into, like "Dance Myself to Sleep," "That's What Friends are For," "In my Room," and all those others. Man, Ernie must be a real weirdo.
