Violent is the Word for Curly (1938)

The stooges are left in charge of a gas station and manage to blow up the car of their first customers, three famous European professors. The stooges steal some of the academics' clothes and wind up at "Mildew", a women's college where the three professors are expected. Mistaken as the real thing, the boys take their place on the faculty. When the real professors show up, the stooges try to convince a rich woman, the schools benefactor, that an athletics programs is more important. Their athletics demonstration comes to an explosive end when the real professors slip them a nitroglycerin basketball.
