Spinelli accidentally calls Miss Grotke "Mama" in front of the whole playground. So to make someone else say “Mama”, they try to do that to Randall, who was with Miss Finster. But Randall wasn’t fooled which got Miss Finster dirty. Many hours later, the students in Miss Grotke's class all said, "Mama" just like Spinelli did.
