That's not weird, is it? We figure everybody on Earth has a crush on Alison Brie in some form or another, and we bet there's a significant amount of people who envision themselves as whatever Alison happens to be eating at the moment. Similarly, there must be people who want to be her bikini, her mascara, or her high heels.
We can entertain the idea of being her shoes, not because we're after Alison Brie's feet, but because her heels have the best view of her panties in that one picture.
