Who are all these people?
Osbornes
That is easy Ozzy and his manager, seen his band live in the 80s.
Cardassians
Antagonists in ST DSN, commonly called Spoon Heads, I think one of Spandau Ballet may have been one, well they did look like Dukat.
AFAIK Hilton is a porn actress, apart from that no idea.
So out of all of these I would recognise the ex Black Sabbath singer and the aliens.
Biting the hand that feeds IT
