Franklin's Word

In "Franklin's Word" from "Franklin," Franklin's little sister Harriet has been imitating him by using the innocent swearing word "stupid." Despite his best efforts, the word slips out in front of his parents and he fesses up that she learned it from him. They explain that little kids like Harriet are fascinated by new words and the best thing is to ignore it, that she really just wants to spend time with her big brother. When she starts to talk about him, he prepares himself for the worst, but she declares him to be the "bestest big brother." He resolves that if he's going to be setting an example for Harriet, he wants it to be a good one.
