When Richard Osman recently asked where people thought the North of England began and where the South of England began, he didn't simply spark a debate.
No, instead he took a thorny age-old question, doused it in petrol and took a match to it.
Because, as it turns out, what constitutes North/South is a complex question of culture as well as geography.
Do the Watford Gap services officially mark the end of the south? Or is the north any place where you say "tea" instead of "dinner"?
One woman - we presume Scottish - even controversially posited that "The South begins at the first shop that doesn't sell Irn Bru ".
Let's take a look at some of the answers...
Money
People - Southerners included - LOVE to harp on about how much more expensive the South (London particularly) is. The difference in the cost of living was a popular argument for North/South demarcation.

Friendliness
If Northerners are to be believed, the South begins with the first random stranger on the street who doesn't smile and extend the hand of friendship to you.

Government funding and employment
Amongst all the good-natured ribbing from each side some more political, sober points were raised.

Pronunciation
We're surprised the old "bath vs barth" chestnut wasn't seized on more.
Lincoln, Derby, Cheshire and Oxford emerged as the most hotly contested cities and counties in the debate.
History, geography and "tea"
All the above are just a small selection of all the impassioned arguments. There were plenty more, such as cuisine (you can still get mushy peas in the South, by the way) and weather .
Why not tell us what you think?
