woo! right up my street! :D i got 70% .. I guess ALF was an american thing? And i didn't even know the pacman ghosts had names ;) ... also, who's Punky Brewster?

The rest are obvious :D

ALF (the ecoterrorrist group) is hardly an American only thing though in other countries they often go by other names.
Unless you mean the TV series which was quite popular over here at the time.
