Tiny Troubles The Little Rascals : Season 17 Episode 8

Alfalfa decides to trade in his unceasingly cranky baby brother for another baby found in the park. They take the baby home and soon find the baby doing rather grown-up things, like drinking beer. The police show up and it's revealed that the baby is Light Fingered Lester, a pickpocketing midget. The gang gets arrested, since the cops think that they're all midgets, too.
