Where Did Jacob Learn That? Oh That's Right, His Daddy.

So the other night we were sitting in the floor and Jacob kept making this noise.  We couldn't figure out what he was doing.  Matthew thought about it for a minute, then remembered he had made that noise a few times when he and Jacob were playing.  So he looked at Jacob and made the noise.  Sure enough, Jacob looked up at him, giggled, then made the noise back to him.  It was hilarious!  I of course got out the camera.  This is what I got before the battery died.
