yeah right

Can someone please tell me if there is any way possible to say the words "yeah right" and not sound sarcastic? I've played these words in my head over and over again and tried different ways of saying it in my mind but they all come out as being sarcastic or condescending.

Yeah right! Yeah right. Yeah right?

It all sounds like you're itching for a fight. There is just no way to say those words and be nice about it. No freaking way.

Is there?
