Warren Buffett -- What's a Kardashian?

Warren Buffett has more important things to worry about than who Kim Kardashian is -- so it should come as no surprise that he really doesn't know what it is she, you know ... does for a living.

How Warren got asked about his feelings on Kim is rather interesting. Buffett, the world's third richest man, is an advocate of increasing taxes on the wealthy. Kim has found herself the target of a group that claims she doesn't pay her fair share of income taxes.

So TIME magazine asked Buffett what he thought about Kim K. His reply: "I've seen her name, but I wouldn't be able to tell what she does but put her name in the paper."
