While the Kardashians have gone through a lot recently, for David Letterman, he only has eyes for one thing: Kim's butt.

The Kardashian ladies appeared on the 'Late Show' Tuesday night where Letterman spent a good deal of air time on Kim's bottom.

The host brought out Kim's x-ray,to which Khloe said, "that's all fat," and tried to get some details, asking--bizarrely--"did it hurt?"

Not to show favoritism, he opened the x-ray question to all the Kardashians and Kourtney said she x-rayed her breasts because she has implants, and she wanted to compare notes.

Letterman responded, "Thank God you had the courage to come forward."
