Just wondering if there is a database or some such out there that lists all the different Aliens, Predator, and Marine references made in tv shows, movies etc?

Such things would include of course the South Park appearances, the Aliens that show up in the one Dresden Files novel, or shows that have "Game over man!".

For instance, I was watching one of the syndicated Simpsons episodes last week, Bart meets the cowboy, and Snake and some other bank robbers all have black Pulse Rifles.
