In a new clip previewing Sunday's episode of Keeping Up With the Kardashians, Kim Kardashian goes back and forth with Bruce Jenner about whose hairstyle looks better. Bruce starts the whole thing by lightly making fun of Kim's messy bun and then Kim fires back telling Bruce he's the pot calling the kettle black. Watch the hilarious interaction, and then make sure to see which sister Kim claimed to have "bought her f*cking career."
