That's insane. Now that's what I would call a win, a big win on something completely unexpected.
I too made a bet on Lay, I mean against Hilary and I won on 3.8 odds, but it was totally unexpected.
The odd that he got the bet for is also insanely high. Even though the odd is quite big for you and him, you should be still very happy that you won too. A lot of people lost ton of money cause they think Hillary will be a sure win and they bet huge amount on it.
