Evil Ezri, I don't think there were many people watching DS9 just for Jadzia -- or her breasts -- and DS9 didn't get canceled, it ended on purpose (as noted upthread). I really think this entire line of questioning is sort of insulting to the actresses, who are more than the sum of their cup sizes. You're basically implying that Nicole DeBoer's failure to get breast implants cost a bunch of people their jobs.
I know that DS9 ending because of choice. Bringing up the topic that people lost their jobs with Ezri, Kes and Hoshi, would say with the conventions of Star Trek. If you look at 7 of 9, thousands of people have made millions of dollars with Star Trek conventions. So if you are employed to promote DS9 after the series, with posters or whatever … is Ezri Dax your dream girl?
