An episode of the TV show
South Park last year had the character Wendy Testaburger denouncing Kim Kardashian as a bad role model for girls:
Kim Kardashian is a short, overweight woman who manipulates her image and makes average girls feel horrible about themselves!
When denounced by a boy as a 'liar' she replied:
Look it up, stupid! In real life Kim Kardashian has the body of a hobbit!

Later in the relevant episode, Ms. Kardashian's fiance, Kanye West, appears to deny that she is a hobbit, but ends up making things worse.
If hobbits existed in real life, how do people think they would respond? Would they regard it as a compliment, turning the insult around? Would they make their own comments about Kim Kardashian, some of them perhaps strong enough for Tolkien not to translate?
