Here's the story: I dressed Kate up in one of her Christmas outfits from Grandma DeAnn. Ryan thought she looked very nice so he said, "You look very nice today Kate." Without missing a beat, Kate said, "Get out!" accompanied by the appropriate arm gesture of pretending to push away the complement. For all you Seinfeld loyalists out there, you might think she's been picking up on some of their lingo, but I'm pretty sure she's never seen Seinfeld. Although she is pretty handy with the controls on the TV, so who knows. We have no idea where this came from, but it sure was cute. So we tried it again, and she did it again.
This is a reproduction, made obvious by the audible, "Ok, go!" at the beginning of the video, but we were still glad to get it on camera.
