"Interjections!" was an animated short in the Schoolhouse Rock! series which aired Saturday mornings on ABC TV. I loved watching these short films which were designed to make learning fun. The lyrics were catchy such as this one from "Interjections!":
"Interjections (Hey!) show excitement (Yow!) or emotion (Ouch!).
They're generally set apart from a sentence by an exclamation point,
Or by a comma when the feeling's not as strong."
