I've got a character in my sitcom, Gary, who's a bit of a dodgy 'wide boy'. He's trying to con someone out of something by tossing a coin. I was trying to think of an amusing line that Gary could say where both options are in his favour. The best I could come up with is "heads I win the book; tails you lose it". But I'm not entirely convinced by it. Anyone got a better line?
Thanks in advance.
