Someone took a picture of Justin Bieber eating a burrito sideways like corn on the cob, instead of holding it the long way and biting into the end. And now the Internet is wondering if Justin knows how burritos work. Or is he onto something? Is there proper etiquette on how to eat a burrito?

Maybe taking a big 'ol bite out of the middle is best because every everything is 'perfect'.  All the ingredients are there and that is the taste the burrito is intended to have. You don't have the "perfect" bite at the top... it usually takes a couple bites to get to where all the ingredients are there. ie: Rice, meat, sour cream, guac, etc.
