Ep 2. Mighty Lak a Goat

When the "Our Gang" kids get their clothes muddy, Spanky concocts a mixture of chemicals that removes the mud but leaves a foul and disgusting odor. The kids can't understand why the teacher won't let them stay in school. When the kids enter a movie theater, all the other patrons leave. Finally, the police emergency squad in gas masks removes them from the theatre and decontaminates them.
