It's the first day of school, and Spanky and Alfalfa have cooked up a scheme to be sent home. Spanky fixes up Alfalfa with a phony toothache by blowing up a balloon in his mouth to create the illusion of swelling. But the new teacher has overheard their scheme. She sends them home, but only after letting them know about the ice cream that's on its way to the classroom.
The toothache miraculously disappears, but the balloon gets caught in Alfalfa's throat. The teacher wants him to sing a song, which he does, complete with a high-pitched squeak every time he inhales.
