Watch Pardon My Clutch (1948) Official Trailer

The stooge's friend Claude sells them his old lemon of a car so they can take Shemp, who is sick with a toothache, camping. The car won't work and the boys are apparently out a bundle, when a car collector happens on the scene and offers to buy it at a premium. Claude backs out on the deal and gives the stooges their money back, only to discover the "collector" is an escaped lunatic.
