So I was looking through IMDB, reading some of the DS9 quotes and came across this one:
[trying to negotiate with a group of Ferengi]
Yelgrun: And I thought the Breen were annoying.
And this opened up a whole can of worms.
I decided to see where that was from and clicked 'Yelgrun' - which took me to Iggy Pop's IMDB page. Iggy Pop was in DS9. Think about it.
Iggy Pop was a character in Star Trek: Deep Space Nine!
Not only that, the quote is from The Magnificent Ferengi (6x10) - which is the episode in which Quark and co rescue Ishka/Moogie from the Dominion.
This, in turn and given the context of the quote, makes Yelgrun a Jem Hadar or a Vorta (I later confirmed him as a Vorta). Which means the Dominion had enough dealings with the Breen for a Vorta to acquire some stereotypical views of them. And this is back in early Season 6. But the Breen didn't join the Dominion till The Changing Face of Evil (7x20).
So not only is there the oddness of Iggy Pop being there, there's also the seemingly innocuous line which foreshadowed the events towards the end of the Dominion War.
I just thought it was worth noting.
