"However, it would be quite easy to beat a Wiganer in a quiz about Wigan!"

Again, a statement to provoke and one which is a ridiculous statement as it is open to being questioned.
The two words (Wiganer and Wigan) could be replaced by other words which have a connection to each other. People do not know everything about a given subject which is vast and can be extreme. Also, some questions can easily be worded in a way which there is not one answer - therefore, the right answer is only available when the person asking the questions allows it to be so.
