More of a segment than a promo, but....
I'll try and find a video later, but my favourite promo was probably about a year ago. It was at a PPV where Candice was the Women's champion still and i think Matt was the US champ and Jeff won as well. Anyway, the Hardy's were backstage patting each other on the back for winning, when Candice comes along says 'Hi guys' and then grabs a bottle of water from a barrell and then starts pouring it on herself, and doing that twirl thing she used to do when she nothing but eye candy. The camera shot keeps switching from her doing that, to the Hardys struggling to keep themselves from drooling all over the place, when suddenly Ron Simmons appears, he looks at the Hardy's with an expression on his face that says 'what's their problem?' and then he turns, sees Candice and his eyes widen, and he, typically says 'Damn!'. But rather than say it angrily like he used to, he says it in a really weak, voice that sounded like the blood was rushing from his head (which it probably was).
This segment went on for about 5 minutes, and i'm thinking 'yeah, she's happy to be exploited. And?' and then Ron cropped up and i laughed my ass off, and then even harder when he said 'Damn' the way he did.
