I know this isn't really a joke or prank, but the look on this baby's face was priceless when she met her dad's twin brother. It just goes to show
you that even young children pay more attention than we realize at times. She knows something is just a wee bit off...
I still remember this, my son have that face, here, there, here, there for a minute,
trying to "know" his real father, but somehow, like that vid, he knows which one.
