If I hadn't just seen what I saw personally, I'd never believe it.
On the broadcast of the "Duke Mayo Bowl," the two ESPN announcers were sampling various food items with mayo. Live, during a pause in the game, they tried Dove Ice Cream Bars dipped into mayo. The one guy immediately retched and hurled into a trash can he grabbed. Absolute silence for about 30 seconds, they must have cut off their mikes. When they came back on, you could still hear the guy retching. I doubt the Duke people were impressed.
