David Letterman doesn’t understand how butt x-rays work. During an interview with the Kardashian sisters on Tuesday’s “Late Show,” Dave asked Kim if her recent posterior pics were painful. “No, you just kind of lay there,” Kim responded. “Kind of like my honeymoon,” Letterman quipped. Although the whole experience was well documented on “Keeping Up with the Kardashians,” Dave was clearly fascinated.
