"No Way Man!"

Yesterday when I saw Jackson jump up and run down the hall I called him into the bedroom and asked him if he needed to go potty. His response was his usual "No way!" This is his favorite sentence by far and cute as anything to hear him say, but since it is totally disrespectful I always try to discourage it. So yesterday when he said "No way!" I corrected him immediately, "You mean 'No ma'am'?" He replied "No way.... Man!"
