"Welcome back to my laboratory, where safety is number one priority." The Crazy Russian Hacker is back, this time informing us that we've all been making sandwiches wrong for our entire lives. He touches on one of life's cruelest truths: bread slices are square, but lunch meat is round. He hates those corners where it's all bread and no meat, and guy, we feel you. Although, we'd like to introduce you to some less plasticky bologna.

You might recognize this zombie apocalypse survivalist and honey mustard enthusiast from his tutorial on how to open a can without a can opener. While today's tip is definitely a little simpler, it's no less useful. Although, we're not sure how covering your "sammich" bread completely with meat is going to save you from zombies. We'll do some research and get back to you on that one.
