My husband wants "man'"naise (he always says it like that) on just about everything. It shows. I once listened to a radio program which said mayonnaise was the number one worst food you could eat. That knowledge didn't phase him.
When I'm mad at him I spread it on extra thick. Fortunately for him, I'm pretty easy going.
Fries dipped in Mayo. It may kill you, but what a way to go.
