New New Yorker cartoon idea

If I drew cartoons for the New Yorker I'd do one of a guy on a horse near a cactus and maybe some antlers or sagebrush or a skull and he'd be wearing a sombrero and a poncho and he'd have a look of total confusion on his face, like he didn't know how he got there or who he was. The caption would be "Mr. Smith has a señor moment."
