Risky business

I know its dangerous to mock the 1st team captain but i've got 20 mins at work to kill!

Roman numerals and the usual 10 digits which we are all used to used in conjuction could throw up a whole new number system. I think i'll catch on pretty quick as will Russell, but for Rowdy who's been sat on his ass at home for yonks is going to get really confused by this new counting system named Flash!
