After all, it's cheaper to head to Taco Bell than it is to dine at Nobu.

Hilarity ensues: Kendall and Kylie Jenner posted fat pictures of themselves on Twitter

But they don't know; to these girls, it's just a lark - cooked up on an application like Fat Booth, no doubt - and who can expect teens to understand the socio-economic conditions behind the obesity epidemic?
Especially when they have Range Rovers to drive, and Hermes bags to flaunt.
Maybe the pair will be able to bag a segment on their mother's new show to share such japes.
