We've heard about butter in coffee and we all balked at that until we tried it and some of us LOVED it! But mayonnaise in coffee?! C'MON! EWWWWWWWWW! How can that even be good? Now granted, we LOVE it on a sandwich, even as a dip for French fries, but in our coffee?! Our perfect cup of morning everything?! Why would we put an oily, egg-based spread into the one thing that starts our day off? It seems awful to us but Helmann's hit Twitter over the weekend and made the suggestion, which completely upended the Internet. And made us question our very existence.
