To be honest, I've never been a big fan of mayonnaise. Some of my friends will defend that goop to the end, but the texture and taste of it just do not appeal to me.
That said, the best way to make me tolerate something is to add a little spice to it and I will admit that the kind of kick you get from KFC's supercharger sauce did more to mend fences between me and mayo than I would've expected.
Although I still wouldn't say I'm wild about it enough to buy a bottle of the stuff, there are obviously many people who disagree with me.
