The Subway Challenge! Can one man get off the Glasgow underground at one stop, race the train to the next and get back on the same train? Mebbes aye, mebbes naw. (What? Want more underground? Here are some great photographs from before and after its 1970s restoration)
Should majorities also have a say? Why doesn't Russia get to vote on Chechen independence? Why can't Britain vote on expelling Northern Ireland ... or the English on Scottish devolution? Should minorities be allowed to hold a gun to the heads of the majority?
