Here's what you do. You go get Honey Boo-Boo's mom, June, and stand her in front of the open refrigerator (don't worry, this isn't a fat joke). Ask her to move items in the refrigerator aside, one at a time. When she screams and runs from the fridge, yelling, "Mayonnaise! Get it away from me! I'm not playing with you! Get it away!" you'll know you've found it. (Or the guys will, anyway.) She supposedly has a mayo phobia. I heard of someone else who did, too...on one of those TV shows about people's fears and stuff, or maybe a talk show. Can't quite remember.
