Cole's New Phrase

"You're kidding me!"  Hu?  Really, did he just use that in context?  Yep, sure did.  We looked outside and saw it snowing and that was the first time I heard him say it.  I've noticed he uses it all the time.  He sometimes will shake his head and say, "You have got to be kidding me!"  Not sure where he picked it up, but it's rather cute.
