Mental Floss has some fun quizzes, where the object is more to be entertained, amused and educated, rather than to try to get the perfect score. Here's a good one: Slogans of Cheap Beers.
Some other fun Mental Floss quizzes:
Discontinued Ben & Jerry's Flavor, or Band I Found on Myspace?
Troy McLure Film, or Actual Terrible Movie?
Scooby Doo Episode Plot, or Actual News Story?
