Mighty Lak a Goat

The gang tries to clean off their clothes after being splattered with mud accidentally by a passing motorist. A "miracle" cleaning solution devised by Billy "Froggy" Laughlin works beautifully, but with one major drawback: The stuff stinks to high heaven! Froggy tells the gang that they would get used to the smell. They do get used to the bad odor to the point of being oblivious to it. The kids manage to empty out a bus trying to board it. (Wikipedia)
