i dont know much about smackdown, so i dont know what vickies situation is, but from what i am lead to believe:
x-pac was a heel back in the day and he got booed hardcore. not because he was a great heel, but everyone was over him and thought he sucked. he didnt get booed in the way mcmahon would. like at the show, a fan would hate on mcmahon hard coz hes an asshole in the storyline, but if u met him in real life, ud be like "mcmahon, you rock!" but in the way of x-pac, ud boo him coz he sucks and then u meet him in real life and ud be like f**k off x-pac, you suck dude.
i think thats it haha
as for ctc, i have no clue.
