One of the rare appearances of rattlesnakes in a romantic comedy, starring Salma Hayek and Matthew Perry. Perry is taking a walk in Mexico with a bunch of Hayak's male relatives who are all carrying rifles. We hear rattling as he walks up to several rattlesnakes that just happen to be lying around coiled up together in the desert in the open sun, which is, of course, nearly impossible. (There is one live snake that appears to be a Southern Pacific Rattlesnake, Crotalus oreganus helleri along with several dead or fake snakes.) When he mentions snakes, the Mexican guys get excited and one of them yells "cascabeles." They rush over and circle him and with cliche bullfight music in the background and all those improbable clicking sounds you always hear when you see guns in movies, they shoot at the snakes and blow them to kingdom come, cowboy style. All done with fake snakes and fake bullet strikes, of course.
