‘It’s funny what a man won’t do to save his own life.’
It was translated in Dutch, but I’ll write the translation in English: ‘It’s funny that a man will do anything to save his own life.’
Probably depends on what exactly you want to say. Let’s assume that the most logical version of the statement is something along the lines of ‘It’s funny to see what a man is willing to do to save his life’. Now, if you want to be sarcastic you can flip this around: ‘It’s funny what a man is unwilling to do to save his own life’.
