One man's ceiling is another man's floor.
There is another man within me that's angry with me.
Never bet your money on another man's game.
I don't trust any man who hasn't kissed another man.
Never touch another man's button.
Always wanting another man than your own.
One man's opportunism is another man's statesmanship.
A man who layeth with another man must be stoned.
Never rub another man's rhubarb.
You don't mow another man's lawn!
