Maybe Sheldon Cooper isn’t that crazy. On The Big Bang Theory, Cooper goes nuts if someone touches his food. In a season two episode, Penny merely touched an onion ring and set off a cataclysmic series of events which escalated to unreasonable (and hilarious) proportions.

All this over an onion ring.

Look at the picture below and decide if you will ever return to Taco Bell. Yes, that is a Taco Bell employee licking a stack of taco shells. While it’s unclear if the shells were intended for customer orders or headed to the trash bin, it is quite disgusting to say the least.

Not unlike the guy who bathed naked in a Burger King kitchen stationary sink and posted it to YouTube. Burger King’s response? A ban on all photography and video in its stores.

Taco Bell responded publicly to the photo, which is burning its way across social media, saying: “We will not tolerate this type of behavior”. They are conducting a full-scale investigation. In other words, look forward to no more Instagram in your local Taco Bell.
