The Three Stooges S05E06 - Violent is the Word for Curly

The stooges work as gas station service men who end up running away from three professors on an ice cream truck. After thawing Curly out from sitting in the back of the ice cream truck the boys put on the professors clothes from their stolen luggage. The stooges are mistaken to be the professors by the college who is expecting them and they poorly pose as the professors and sing their famous ""Alphabet Song"". The real professors show up, but the ladies in the ""girls-only"" college end up getting their athletic program thanks to the stooges.
