What are some "impossible" online quizzes?

Some ?impossible? online quizzes include ?The Impossible Quiz? and ?The Impossible Quiz 2.? While both quizzes are not actually impossible, most people who play them never reach the end.

?The Impossible Quiz? series of games is a collection of free online Flash games. Players are asked a series of mind-bending questions, and they must think outside the box to answer them. Very few of the questions are based on actual knowledge. Instead, players often need luck to answer the questions correctly. Most players have to play the game multiple times and remember what the right answer is for each question to progress, which is why these quizzes are considered to be ?impossible.?
