What's the Matador?.

The stooges are actors traveling to perform at a fiesta in Mexico. After they accidentally switch suitcases with that of Dolores, a lovely senorita they met on trip down, they must sneak into her house to retrieve their suitcase. When they are confronted by her jealous husband he vows to kill them if he sees them again. At the fiesta where they are performing a comedy bullfight (Curly is the matador, Moe and Larry are in a bull costume) the husband bribes the attendants to let a real bull into the ring. Curly knocks the bull out with a head butt and becomes a hero.
