Kim Kardashian guest-stars on '2 Broke Girls': Why does she still get these gigs?

Kim Kardashian will appear on the fourth season premiere of "2 Broke Girls" on Monday night, which brings up the logical question: Why? This is the latest in a long line of TV cameos for the reality star, and let's face it, you don't cast her for any acting skills. Theoretically, you cast her to get buzz and ratings -- at least, that's what shows including "How I Met Your Mother," "CSI: NY," "Drop Dead Diva" and "Last Man Standing" were hoping in the past with a Kim appearance.
