Cantinflas is the boyfriend of Paz, the household maid of Cayetano Lastre. It is dinnertime and Cantinflas is waiting outside the mansion for Paz's whistle: a sign for Cantinflas to enter the kitchen to eat. This is because there is a dog in the front yard named "Bobby", and Paz's boss is unaware of Cantinflas's forays into the house. While waiting, another man also arrives to do the same, pulling out a cigarette and dropping his wallet in the process, which Cantinflas picks up when entering the house. Though like other times Cantinflas goes straight in to eat, this time his girlfriend has a favor to ask him: to kill the dog "Bobby" who has suffered a sudden onset of rabies and doesn't let Cayetano leave for an appointment. Seeing his hesitation, Paz is adamant: if he does not kill the dog, he does not get to eat. Cantinflas is nervous about the idea, but eventually kills the dog with a gun.
