Who wants to be a millionaire?

The popular TV show has been shown all over the world for quite some years now, and that means Youtube is full of clips with people screwing up. :) Here is a little selection:
1. A ‘cool’ college dude proudly screwing up on the first question.
2. Apparently French people don’t know a whole lot about the universe .
3. British people don’t know the traffic light sequence.
4. The contestant is the only one who does not know the right answer to the question.
