The Little Rascals S21E02 - Mighty Lak A Goat

The gang gets splattered with mud by a passing motorist while walking to school. Froggy takes them to his garage where he's created some cleaning fluid with his chemistry set. The stuff works like a charm, but stinks terribly. Before long, the boys get used to the smell, but find that they're unwelcome on the bus, in the schoolroom, and in the local movie theater.
