Tell me this a-dev, I have had numerous people tell me that if they were ever on 'Who Wants to be Millionaire' and they were on a high number and a footie question came up then I would be the person they would phone, so same scenario to yourself buddy, your best mate is going for the million bucks and he has a 'phone a friend' lifeline left and the question is T2 related so he naturally phones you with a smile on his face and the questions hits you.....would you blow it?
My god imagine if I did. I don't know everything about Terminator, probably far from it. But if that situation arose I'd be most confident out of all possible topics that I could answer a Terminator or Star Wars question correctly. My knowledge elsewhere is appalling, I better be able to answer a question about those.
