The Simpsons Season 1 Episode 11

Bart flushes a cherry bomb at school, nearly injuring Principal Skinner's mother, Agnes, in the process. An exasperated Skinner tells Homer and Marge that since expulsion would not do Bart any good, he's placing him in a foreign-exchange student program. Bart is sent to France, where his host family are unethical winemakers who plan to employ him as a slave.
