Jackie Cooper and Miss Crabtree; in the case of Jackie Cooper, Hal Roach oversaw his contract being sold to another film studio in order to ensure Cooper continued success.
Alfalfa, Spanky, and Darla also count.
Heartwarming Moments: "Teacher's Pet", full-stop. Jackie hitches a ride to school with a kind, attractive young woman and tells her all about his plot to make his new teacher, Miss Crabtree (who he assumes to be a mean old hag) absolutely miserable on the first day of class, complete with a complex scheme to leave school early with his friends...not knowing that the young woman *is* Miss Crabtree, and that she was planning a cake and ice cream party for the students for their first day back at school. When he finds out after they spring their plot to get out of class, his friends go back into the classroom and fess up and get cake/ice cream. But Jackie, horrified that he had unwittingly badmouthed the teacher to her face, opts to sit under a nearby tree in the playground and cry over what he had done. At which point, Miss Crabtree comes out with two plates of cake and ice cream for Jackie, as well as an unspoken willingness to both forgive him and offer him a second chance.
